Dear Ms. Eastin:

We have recently learned of plans to install a 500 foot radio tower near WCR 49 and
WCR 18.
At this time, I would have to question the safety factor evident in placing such an obstruction
in close proximity to a public use airport facility. I have not received any correspondence from
the FAA regarding the installation of a tower which would directly affect our air space. In the
past, the FAA has notified us in advance for any comments or objections to radio or
microwave towers which would affect the safety of incoming or departing aircraft traffic.
Thank you for your time in reviewing this concern.
Sincerely,
Marilyn Taylor

Kerri Keithley, weld County Planning Department, has provided
me with a copy of your letter of April 12, 1997, in which you
expressed concern about our proposed radio tower on wCR 49
north of I-76. I advised Kerri, the current planner on our
project, that I would make contact with the FAA concerning
your letter.
Earlier today I spoke with Mr. Ted Melland of the System
Management Branch, FAA ANM-530, Northwest Mountain Region.
Mr. Melland told me that following our application, submitted
by our Consulting Engineer, Timothy C. Cutforth, P.E., on
February 5, 1995, the FAA did their Aeronautical Study and
that your airport over 9 nautical miles away was included.
It was April 5, 1995, that Ted Melland signed off on our
application after FAA determined that our proposed tower
would not be an obstruction and would not be a hazardto air
navigation. A copy of this determination is enclosed for
your files.
If you wish to speak with Mr. Melland about this matter he
may be reached in Renton, Washington at 206-227-2530.

Good Morning Bob;
Concerning a request to build a tower for an FM station
booster to serve the Hudson area.
The requested tower height and location were selected
carefully based on many federal government requirements and
several practical considerations.
SITE SELECTION CRITERIA
The tower site is restricted by a federal law that requires
a booster or translator to be located within the predicted
primary coverage of the licensed station it is to repeat. It
is also required to keep its predicted coverage within that
same station coverage area. As the tower site is moved
closer to the edge of the coverage area the potential area
where the signal can be improved for the listener le reduced.
Therefore the tower cannot be moved to the south or west
without seriously reducing its potential service to the
public.
Secondly, the tower location must be near the community to be
served in order to provide a reasonable good quality of
service to the target community, in this case Hudson,
Colorado. The farther the tower is from Hudson the less
signal will get back to Hudson and its surrounding area.
Therefore a site further to the North or East will not be
able to provide a strong enough signal for good reception on
inexpensive table radios in Hudson.
Thirdly, the cower location was picked to be atop a small
hill in order to provide good line of sight conditions to the
Hudson community. FM radio aignals are absorbed by dirt and

trees and when the view is obstructed towards a community the
signal quality is seriously degraded. A lower site or a
lower tower would not provide a quality signal to all of
Hudson and the surrounding area at the allowed operating
power.
Fourth, the site was selected specifically to be outside of
any heavily populated area to minimize the number of
receivers within the nearby overload area. Transmitters do
not automatically interfere with all receivers but in some
cases the signal very close to the tower (perhaps in the
first half wile or so surrounding the tower) will be strong
enough that some receivers cannot reject it. A translator or
booster station is not allowed by federal law to interfere
with actual reception of radio signals. Therefore, the
applicant will be required by federal law to remedy any such
actual interference if it should occur- The selected site
will minimise the possibility that actual interference Could
occur.
TOWER HEIGHT
The proposed tower height was approved as not a safety issue
by the Federal Aviation Administration. The FAA does require
that all towers above 200 ft tall be painted aviation orange
and white and be lit with red beacons to make it clearly
visible to pilots flying in the area. This tower has a
standard painting and lighting requirement.
The tower height directly affects the coverage and was
selected to provide a clear unobstructed view towards Hudson.
As discussed above the tower height is directly necessary to
provide high quality service to Hudson and the surrounding
area.
RF POWER DENSITY EXPOSURE
The FCC has set standards for RF power density exposure to
the public and published them as OST-65. The proposed
facility will have less than 0.01% of the maximum RF power
density on the ground in the area surrounding the tower.
Translators and booster facilities rarely approach the
federal limits due to their relatively low power.

SUMMARY
The proposed site uniquely meets all of the federally imposed
criteria as well as the practical criteria. I believe the
tower site and the tower height are the best combination
available to provide a quality radio service to the public.
Respectfully,
Timothy C. Cutforth P.S.
