DANETTE MOORE, PLANNING COORDINATOR
CONSIDER APPROVAL OF A RESOLUTION
APPROVING A CONDITIONAL USE PERMIT TO
ALLOW AN AMATEUR RADIO ANTENNA TO
EXTEND 25 FEET ABOVE THE STRUCTURES
HEIGHT
Historv: Mr. Baechler, the applicant, has applied for a
Conditional Use Permit to allow for the placement of an
amateur radio antenna on the roof of the garage located at 6346
Conroy Street. The property is located within the R-1 (Low
Density Residential) Zoning District and is guided R-L/MD
(Low to Medium Density Residential) on the Comprehensive
Land Use Plan Map.
Antennas are a permitted use in all Zoning Districts.
According to Section 1110.503 of the City Code: "Subject to
approval of a conditional use permit, the City Council may
permit antenna heights of up to 25 feet above the structure if
the applicant can demonstrate that, by a combination of
antenna design, positioning of the structure and/or by
screening erected or already in place on the structure, off-site
views of the antenna from adjacent properties are minimized. "
The Planning Commission considered this request at a public
hearing on June 27, 2005. Mr. Johannas, an adjacent property
owner, spoke at the hearing and expressed concerns related to
visibility from his home. The Planning Commission stated that
they felt the applicant had adequately mitigated the visual
impacts of the proposed antenna and voted to recommend
approval of the conditional use permit. Draft minutes of the
Planning Commission meeting are attached to this report
(Exhibit R).
Phvsical Site Characteristics:
Total Site Area: The site is 0.50 of an acre.

Phone 952.447.4230 / Fax 952.447.4245
Adiacent Existine Uses: The site is bordered by parcels
zoned R-I (Low Density Residential) and guided R-L/MD
(Low/Medium Density) on the 2020 Comprehensive Land Use
Plan Map to the north, west, and east. The site is bordered by
Prior Lake to the south.
ISSUES:
The applicant would like to construct an antenna on the
existing garage located at 6346 Comoy Street (Exhibit A). The
narrative (Exhibit B) details the purpose of the request. The
applicant's site contains a single family dwelling and an
attached garage. There is a 22.5 foot separation between the
garage and house roof, with the house roof having a height of
6.5 feet taller than the garage roof (Exhibit C). The applicant is
proposing to construct an antenna that extends 24 feet above
the highest point of the garage roof (Exhibit D). If the
applicant was to construct an antenna of 15 feet or less above
the highest point of the garage roof, the applicant would only
be required to obtain a building permit. However, the applicant
has indicated that the additional 9 feet is necessary to
accommodate the essential antenna components for adequate
reception. The proposed antenna is made up of the following
four components:
1) Tower base (Exhibit E): An engineered base that will be
grounded to the trusses of the garage roof. The tower will
extend 7.5 feet beyond the top of the garage roof.
2) HF Y AGI Elements (Exhibit F): The center component / bar
(boom) will not extend more than 19 feet across. The element
bars will extend out from the boom. Five elements will be
attached, with the largest element being 31.6 feet in length.
The space between the top of the tower base and the top of the
HF Y AGI antenna component will be 6.5 feet.
3) 144 MHZ Elements (Exhibit G): This antenna component will
have 13 element bars attached to a center boom bar of 15 feet
in length. The space between the HF Y AGI antenna and the
144MHZ antenna will be 5 feet.
4) 144 MHZ / 440 MHZ Vertical (Exhibit H): The dual base
antennas located at the top of the structure will extend 5 feet in
height.
The applicant has provided structural documentation
demonstrating that the structure has been engineered by a
structural engineer. A building permit will be required prior to
the construction ofthe antenna.

The applicant has indicated that other locations were
considered. However, in order to maintain setbacks from
adjacent property lines, and to limit visual impacts, the
applicant is proposing the garage roof location. The antenna
will be located on the roof to maintain a 25 foot setback from
the center of the tower base to the nearest property line
(Exhibit n. No portion of the antenna structure will extend
across the property line.
The applicant distributed a letter and met with several of his
neighbors to educate them on his proposed antenna. As a
result, the applicant received the signatures of five neighboring
property owners, stating that they had met with Mr. Baechler
and were not opposed to the antenna (Exhibit J). In addition,
staff has been contacted by two individuals who have
expressed concern related to the following items:
Height / Visual Impacts: Section 1110.503(2) of the Code
states, "Amateur Radio Antenna. In accordance with the
preemption ruling PRB] of the Federal Communications
Commission, towers supporting amateur radio antennas that
comply with all other requirements of this subsection are
exempted from the height limitations of the subsection up to a
total height of 70 feet, provided that such height is technically
necessary to receive and broadcast amateur radio signals."
Section 1110.503 (2) would allow the applicant to construct a
tower with a height of up to 70 feet in height on the lakeside of
the home. However, the applicant had concerns that this may
create a greater visual impact.
The applicant has supplied elevations of the existing structures
and overlaid the proposed antenna to scale (Exhibits K-O).
The photos were taken in the spring and reflect beginning
season foliage.
The applicant has considered options for using coloration to
camouflage the proposed antenna. After researching the
camouflage tones used by the U.S. Military for personnel in
urban environments, a grey tone was established as the most
effective color to mask the visibility ofthe antenna (Exhibit P).
Health Impacts: The antenna will utilize radio frequency
electromagnetic (RFEM) fields. Human exposure to RFEM
energy and microwaves has become frequent as a result of
radio, television, microwaves, cell phones, and alike. The
Institute of Electrical and Electronics Engineers-United States
(IEEE-USA) provides scientific data used to regulate and
determine acceptable levels of RFEM energy. According to
L:\05 FILES\05 CUP\Bud Baechler\CC report.doc 3
q ~ .........~--.-._....--. ,.... ..., ,.., ... _. _. .. .... .
the IEEE-USA standards, operation of the proposed antenna
will not exceed acceptable levels ofRFEM energy (Exhibit Q).
Interception Interference: Staff has attempted to establish if
neighboring structures can anticipate experiencing any
interception interference when the antenna is in use. This
aspect is inconclusive. Numerous contradictory studies exist.
However, it is conclusively shown that the taller the
antenna/tower, the less likely the adjacent uses are to
experience interception interference.
CONDITIONAL USE PERMIT FINDINGS:
Section 1108.200 of the City Code sets forth the general
criteria utilized to review a CUP application.
(1) The use is consistent with and supportive of the goals and
policies of the Comprehensive Plan.

Council may permit antenna heights of up to 25 feet above the
structure if the applicant can demonstrate that, by a
combination of antenna design, positioning of the structure
and/or by screening erected or already in place on the
structure, off-site views of the antenna from adjacent
properties are minimized." The applicant has utilized
camouflage coloring, tree cover, and location to mitigate
impacts to adjacent properties. Ifthe Conditional Use Permit is
granted, the use will be consistent with the intent and purpose
of the Zoning Ordinance and the R-l district.
L:\05 FILES\05 CUP\Bud Baechler\CC report.doc 4
In addition, in a Memorandum Opinion and Order in PRB-1,
the Federal Communications Commission (FCC) has
acknowledged "that local authorities can regulate amateur
installations to insure the safety and health of persons in the
community, but believe that those regulations cannot be so
restrictive that they preclude effective amateur
communications."
(4) The use will not have undue adverse impacts on
governmental facilities, services, or improvements, which
are either existing or proposed.
The proposed use will not have undue adverse impacts on
governmental facilities.
(5) The use will not have undue adverse impacts on the use and
enjoyment of properties in close proximity to the
conditional use.
The applicant has considered alternate locations, tree cover,
and camouflaging color to limit the impacts to adjacent
properties. The use will not have undue adverse impacts on the
use and enjoyment of properties in close proximity.
(6) The use is subject to the design and other requirements of
site and landscape plans prepared by or under the direction
of a professional landscape architect, or civil engineer
registered in the State of Minnesota, approved by the
Planning Commission and incorporated as part of the
conditions imposed on the use by the Planning Commission.

Brief Description of Proposed Proiect
L. F. Bud Baechler
6346 Conroy Street, NE
Prior Lake, MN 55372
As a federally licensed radio amateur of more than thirty years, I dedicate about 90% of
my radio activity to public service. My wife, Becky, and I are certified SkyWam weather
observers and have provided weather-related communications during local conditions of
sever weather watch and severe weather warning. I also handle communications
between South American missionaries and their friends and relatives in the United
States.
Having purchased a home in Prior Lake, we have made this our permanent residence.
We are now at the stage of moving my amateur radio equipment and antennae to our
new home. I have been working with the City of Prior Lake to arrive at a suitable
antenna location and configuration that can be achieved within the provisions of the
existing ordinance subsection governing such matters. We have concluded that a
garage roof mount and a height limit of 25 feet, or less, would conform to the existing
regulations provided that a Conditional Use Permit is granted.
I am applying for a Conditional Use Permit so that I can erect an amateur radio structure
on my garage roof to a height of 24 feet above the structure. If the height above the
structure had been 15 feet, an ordinary building permit would have been sufficient.
As the information in this booklet will document, I have met the requirements of the
Conditional Use Permit application including approval of a Minnesota state licensed
structural engineer and have complied with the requirement of advising neighbors within
350 feet of our property. I have visited in person with many of the neighbors, each of
whom has no objection to this project and have indicated their support. In particular, I
have received affirmation from:
Joe Scott
Owen Paulkner
Cal Chadwick.
There are two critical reasons for requesting a height of 24 feet:
1. Radio transmission and reception performance is directly proportional to antenna
height. Appropriate and typical heights for amateur antennae range to 75 feet or
more. The conditional Use Permit height limit is 25 feet. I am conforming to this
limitation.
2. There is an engineering design requirement that the space between individualeantenna elements be a distance of one-quarter wavelength of the antenna's

-Projected Area is the actual (flat) projected area of either the elements or
boom (highest value) without any shape factor included. This area may be
used with EIAlTIA-222-0 and later versions and with the USC formulas to
determine tower and mast loading. On HF beams, the element area is
usually higher. On VHF/UHF beams, the boom area is usually higher. When
stacking HF and VHF beams, use the element area of all beams at their
attachment points to determine loading at zero degrees to the boom axis.

Far Field Power Density Calculation
From PWR_DENS V3.2 by E. S. Parsons, K1 TR
SITE: 6346 Conroy Street NE, Prior Lake, MN 55372
INPUTS:
Maximum Output Power from Transmitter is 1000 Watts.
Antenna Gain Over a Dipole is 7.8 dBd.
Frequency of Operation is 14.0 MHz.
Total System Losses are 1.8 dB.
Distance to Antenna is 58 feet.
--)
'V"
'-'0.
"''-.
,
-~
5f)1
OUTPUTS:
Power at Antenna Feedpoint is 662.2 Watts.
Effective Radiated Power is 6544 Watts.
IEEE C95.1-1991 Maximum Limit is 0.92 mW/sq em.
Computed Power Density is 0.165 mW/sq em (1.649 W/sq meter).
(Power density calculated along antenna boresight in free-space;
no assumptions made about antenna pattern.)
Hence: 1. The Computed Power Density is 18.0% of the
C95.1-1991 Limit.
2. The Computed Power Density is -7.46 dB from
the C95.1-1991 Limit.
3. Transmitter output power must be increased by
at least a fador of 6 to exceed the C95.1-1991 Limit.
INTERPRETIVE COMMENTS:
Far field power density is a measure, in units of milliwatts per square centimeter (mW/em2), of the
radio frequency power to which a human or animal is exposed. To put this in context and add
meaning, the power density at the point specified (usually the home closest to the amateur's
antenna) is compared to the Maximum Permissible Exposure (MPE) for uncontrolled
environments set forth by the FCC in their 96-326 Report and Order.
An uncontroled environment is an area where people would not normally be aware of potential
RF exposure. A neighbor's home is an example of an uncontrolled RF environment. The FCC
96-326 Report and Order adopted the standards set forth in IEEE C95.1-1991 for uncontroHed RF
environments.
This analysis assumes that the antenna is pointed at the nearest dwelling. For rotary antenna
systems, the antenna is often pointed in other directions, resulting in much lower power densities
at the nearest dwelling.
The FCC regulation for uncontrolled RF environments requires compliance with MPE standards
for the average power density computed over a 3O-minute period of RF emissions. The power
density for your station (computed above) assumes you are transmitting 100% of the time.
Realistically, transmission modes such as SSB and CWare less than 50% duty cycle whereas
modes such as FM and RTTY are somewhat more than 50%. Also, since typical Amateur Radio
operation is at least 50% listening, most actual duty cycles are well less than 50% over a 30-
minute period. Realistic transmission duty cycles needs to be considered when determining
actual RF exposure over this period.

Human Exposure to Microwaves and Other Radio Frequency Electromagnetic Fields

Summary
(Presented without edit.)
Although there are many beneficial applications of radio frequency and microwave technology,
the Institute of Electrical and Electronics Engineers - United States Activities (IEEE-USA)
recognizes that there are concerns about possible health effects associated with exposure to
microwaves and other radio freauency electromat!netic (RFEM) fields (3 kHz - 300 GHz)
emitted by various facilities and devices. Safety standards, recommendations and guidelines for
exposure to radio frequency and microwave energy have been developed independently by a
number of international and national Organi7.atiOns including the American National Standards
Institute (ANSI) and the IEEE (ANSI/IEEE C95 .1-1992). These guidelines have been developed
by panels of scientists and medical experts to protect human beings from known harmful levels of
exposure to RFEM fields. Based on oreseDt lmowled2e. the IEEE 5IeDOI1s the COIIChIsioB
that eIDOSure at or below the levels recommended in ANSIJIEEE C95.1-1992 is not barmful
to humaD health. The IEEE recognizes, however, that some gaps remain in our knowledge of
biological effects. Therefore, the IEEE-USA supports continuing research to ensure the safe use
of RFEM energy.
Human beings utilize and depend on devices that generate microwaves and other radio frequency
electromagnetic (RFEM) fields (3 kHz to 300 GHz) for their personal, social, and economic well-
being. Aoolications of RFEM eDel'1!V that are readily rPr-w.ed iIlducle radio and television
broadcasting, point-to-point microwave radio (Iong~ telephone and data trammI~on),
mobile radio including cellular telephone, paging and radio dispatch, ship to shore radio,
amateur radio. and citizen's band radio, navigation (ship and aircraft), and radar (military and
civilian use for detection and guidance, flight surveillance around airports, weather surveillance
and prediction, traffic speed control). Applications in the home (cooking), industry (~ing and
drying), and medicine (diagnosis and treatment) are burgeoning.
Tbe stren2ths of fields to which most of the North Americaa DODUIation is emosed are
bundreds of times below current nideliaes for safe em8SIII'e as n:ce-~aded Iw ICft:I aI
national aDd international o~tions. with the exception of individuals in some
occupational specialties. However, the prevalence of man-made RFEM fields and their relatively
recent introduction into the environment have led to concerns about possible adverse health
effects. The answer to such concerns lies in rigorous research and objective assessment of
laboratory and epidemiologic data.

5. Public Hearings:
Commissioner Lemke read the Public Hearing Statement and opened the meeting.
A. EP 05-163 L.F. Bud Baechler has submitted an application for a Conditional
Use Permit to allow an amateur radio antenna with a height of 24 above the existing
structure to be constructed at 6346 Conroy Street NE (R-1 Zoning District).
Planning Director Jane Kansier presented the Planning Report dated June 27, 2005, on
file in the office of the City Planning Department.
L. F. "Bud" Baechler, the applicant, has applied for a Conditional Use Permit to allow for
the placement of an amateur radio antenna on the roof of the garage located at 6346
Comoy Street. The property is located within the Rl SD (Low Density Residential-
Shoreland District.)
Mr. Baechler has been a licensed radio amateur for more than 30 years. Ninety percent
of his radio activity is for public service. He and his wife, Becky, are certified weather
observers and have provided communications during severe weather watches and
warnings. Baechler also handles communications between South American missionaries
and their family and friends in the United States.

Exhibit R
Planning Commission Meeting
June 27, 2005
The applicant's site contains a single family dwelling with a 22.5 foot separation between
the garage and house roof. The house roof is 6.5 feet taller than the garage roof. The
applicant is proposing to construct an antenna that extends 24 feet above the highest point
of the garage roof.' If the applicant was to construct an antenna of 15 feet or less above
the highest point of the garage roof, the applicant would only be required to obtain a
building permit. However, the applicant has indicated the additional 9 feet is necessary
to accommodate the essential antenna components for adequate reception. Baechler has
provided detailed information on the construction and design ofthe antenna.
The proposed height of the antenna is allowed in the district, with approval of a
conditional use permit. In order to meet the above-listed criteria, the Planning staff
recommends the following condition:
· The applicant must receive a building permit prior to any construction on the site.
The Planning Commission's action is a recommendation to the City Council. There is a
provision in the ordinance that did not change with the amendment to the Conditional
Use provision. This will go before the City Council on July 18, 2005.
Questions from the Commissioners:
Lemke:
· How tall is the total antenna structure as it sits on top the garage? Kansier said
staff did not have the top of the garage height however from the top of the garage
to the tip of the antenna would be under 25 feet.
· Could the applicant construct a freestanding 70 foot structure? Kansier responded
he could in the rear yard of his property. In this case, it would be the lake side.
Comments from the Public:
Applicant Bud Baechler, 6346 Comoy Street, moved to Prior Lake last August. Beachler
explained he and his wife were involved in community services for amateur radio, most
of it in communications for military personnel and missionary families. The Baechlers
are also Sky Warn weather watchers who work with the National Weather Service and
local law enforcement officials.
Beachler said they looked at many communities and found Prior Lake to suit their needs.
He recognized the staff in City Hall for their professionalism and felt they were a
reflection of the community.
This is an application for a hobby that has a serious motive. The amateur fraternity is
self-policed and self-governed and operates at a high technical and operational level.
Their participation in Sky Wam Weather is very important.

Planning Commission Meeting
June 27,2005
Beachler gave a brief background on constructing towers and the process he was going
through with the City. He wanted to be a good neighbor and do everything correct. A
license structural engineer has scrutinized the plan with supporting information in the
report. Beachler contacted the neighbors and welcomed any questions and/or cominents.
A supporting list of neighbors were included in the planning packet.
One concern of a neighbor was a health risk of the antenna and radio waves. Baechler
pointed out studies concluded there would be no health concern. Those neighbors have
signed a statement in support ofthe antenna. Baechler has been a Federal licensed
operator for over 30 years. He and his wife take their responsibility seriously in
providing the public service. The Baechlers invest their own money in the equipment
and associated costs. Baechler explained the limited period oftime of operation. It
would depend upon the need. By 4:00 p.m. this afternoon, there were no complaints or
concerns at City Hall for this CUP. There is a level of comfort from the neighbors.
Billington complimented the applicant on the depth of research for this request.
Billington questioned interference with cell phones. Baechler explained the frequency
range for cell phone operation is considerably higher than radio frequencies. If there
would be any kind of interference he will act immediately to correct the problem.
Billington questioned if a professional contractor would install the structure. Baechler
said the construction will meet all City and Federal requirements. Typically amateurs
tend to be "tool" people. He will be assisted by professionals in the installation ofthe
antenna. He is not worried about any engineering concerns as they have all been
addressed.
Baechler explained the "elements" and "booms" on the antenna. The height from the
blacktop to the top of the roof is 15 feet.
Perez questioned what the radio could interfere with. Baechler said generally it would be
Channel 2, a few cases on phones but that has been traced to a telephone company flaw.
It is an easy fix. Cable television has reduced interference problems.
His original mission was to do it right. He wants to complete the project with everything
in place.
Mike Johannas, 6362 Wild Oak Terrance, said his only problem is the visibility of the
antenna from his deck. He did not care to look at the antenna and would like to have it
concealed as much as possible. The project is impressive however he would prefer not to
have the additional antenna length to block his view of the lake.
Baechler said he valued the neighbor's comments and explained the tower setup. The
last bit oftower is pencil thin from his view. The camouflage color conforms to the
military research as the most effective color to mask the visibility of the antenna. There
are also huge trees above the garage blocking the view of the antenna.

Kansier presented pictures from Mr. Johannas' residence.
The public hearing was closed at 7:10 p.m.
Comments from the Commissioners:
Perez:
· Agreed with Billington regarding the work and research that has been done on
this item. As far as the Findings - agree with staff s report. The criteria has been
met.
· The applicant would take immediate measures to correct any problems.
· The applicant has done as much as he can to reduce the impact to the neighbors.
· It is good plan and will support.
Ringstad:
· The applicant has compromised - understands Mr. Johannes' concern. However,
the tower location is a compromise. The antenna could be 70 feet high.
· The applicant has done an excellent job in researching the process.
· Agree with Perez and support the request.
Billington:
· This application meets the criteria in all regulations.
· Agree with the neighbor with the view situation, however the applicant has
compromised in all aspects.
· The color and size will be acceptable. The top 5 or 6 feet (tower) will be pencil
thin from a relatively short distance.
· In view of the way it has been presented - care of the structural and engineering
detail - will support.
Lemke:
· The applicant has met the Findings and specifically the screening ordinance.
