American Transmission Company built and activated a 345KW line right 
thru Madison, WI two years ago.  Huge towers, huge green glass 
insulators.  The line runs right past my XYL's office window, about 100' 
distance.  Once activated, I used a Gauss meter to measure the magnetic 
field in her office - unmeasurable with the background AC fields from 
office wiring and computers.  The highest readings were near light 
switches and a few old CRT monitors.

Also, I drive right under the lines every day on the Beltline Highway in 
Madison, no effect on Madison Stations and I can even listen to the big 
AM radio stations in Chicago about 150 miles distant.

I have much more power line noise along the secondary roads with lower 
voltage distribution 2.3KV to 68KV lines.

You can read about it here:

So I'd recommend that you not "pull up stakes".

BTW, the local utilities companies are converting their water, gas, and 
electric meters to "RF remote read".  The same people that fought the 
power line are now fighting the water, gas and electric utilities saying 
that their "meters are bathing them in radiation that could cause cancer 
right in their own houses". Baloney!

Also, the cellular telephone companies have been putting cell-site 
antennas on the light towers at local school sports stadiums - providing 
revenue to the schools.  Due to an outcry by the same group people, the 
city has now outlawed cell phone towers on school property.  More 
Baloney!

I go to Radio Club meeting attended by many healthy 70, 80 and 90 year 
olds that have been sitting next to their rigs, amps and antennas since 
they were kids and are still healthy.

So I'm not too worried and magnetic fields and RF.
