I suggest you read the following article:
"Front-end Overload, A Worst Case Example" by John Stanley, K4ERO, page
214-217, The ARRL Antenna Compendium, Vol 3.
Here is a quotation from the article that I believe relevant to your
situation.
"For 13 years, I lived on the transmitter site of HCJB, the shortwave giant
in Quito, Ecuador. At distances of from 100 to 1000 yards from my QTH were
over 20 antenna systems. Typically, 10 of them at any given timer were
broadcasting with 10 to 500 KW each. The RF intensity in my yard at ten
feed above the ground was about 10mW/cm2, which at that time was the
accepted limit for human exposure to RF! Today, the limit is about 10 times
more strict at most high frequencies. It is safe to say that no one is
likely to have a worse problem than I lived with. If you do, you should
consider moving!"

Subject: [Towertalk] Moving To New QTH
Has anyone on the list lived near, very near a 100,000 watt FM broadcast
station tower? I have a unique housing situation. I am a Deputy Sheriff
and currently live on the grounds of an elementary school where I
provide "security" for the school building and grounds. This has been a
good deal for me economics wise. Free lot rent, free electricity, free
garbage disposal and free water and sewer. The only real drawback has
been not being able to erect any real antennas. Now for the problem. The
school board has decided and is in the process of building a new school
and will possibly close the school where I currently live and most
likely sell the building and property. No, I can't afford to buy the old
school.
I may have an opportunity to move the trailer I own and live in to
another site, that being the grounds of an FM broadcast station. The
tower is approximatley 1200 feet tall and has a 100,000 watt transmitter
on it. The output power may not actually be 100,000 watts, that may be
E.R.P. In any event, it's a high power FM station operating at 107.3.
There is ample room at the site for me to locate my trailer away from
the tower to avoid any possible damage or injury in case of a freak ice
storm. I would like to talk to anyone who has had a ham station located
"close" to a tower like this to find out if there were any RF problems.
You can either reply to the list or to me directly.
