[TowerTalk] [RFI] 115 KV Lines

[kd4e]

We are on an approx. 330' wide 1500' long 10ac lot.

There are 45K lines up one side that are about 10yrs
old, they were in place when we bought the property.

They are very quiet and the only hassle is one may
not erect anything permanent on that land and whatever
is there is subject to truck damage should they ever
need to service their wires.

The only antenna hassle is that one should avoid any
long-wire antennas parallel to the lines.

I wonder if the windmills may cause some flutter to
ground-wave signals from that direction the same as
airplanes sometimes do to TV signals?

BTW:  I copied this to the TowerTalk list as there
are some folks there who likely have good info for
you.
