[RFI] Towers/Antennas Near 138kV Transmission Lines

[Missouri Guy, N0TT]

Larry,

You are almost guaranteed to have noise if you intend to operate
close to a HV transmission line.  I've never passed under a RF 
quiet HV line except one in northern Quebec that was carrying 
HV DC!  

The only reason I can think of RE: quieter than "residential"
lines is that the HV cross-country poles/insulators are more 
widely spaced and have no customer "taps" on the line.  That
said, there is no guarantee that sometime in the future you won't 
have devastating noise from a HV line that may be RF quiet 
now....and such noise may take months to get repaired.

Keep looking for a more ham-friendly environment.

My 2-cents worth.  :)

73,
Charlie,  N0TT
