I recall reading on the RFI reflector that HV transmission lines are
rarely a problem, or at least not for long, because power companies lose
real money when power leaked, so they had a strong incentive to repair
problems as soon as possible.
I have two 500 kv transmission lines that run beyond the entire west
edge of my property about 200 feet away, and a 7500-volt secondary
distribution line in an easement right on the property line. Initially I
thought one or both was giving me trouble, but I took a 136-MHz DF rig
out there and established, to my satisfaction, that the transmission and
the distribution line were not the problem. At least in this vicinity,
a far bigger problem is old distribution hardware - transformers,
lightning arrestors and so on, which the power company plans to attack
wholesale next week. It will be interesting!

Jerry,
I'm sure you can make something work. I used to have HV power lines about
150 yards from my house.
It was only a problem during rain/snow/fog with conduction across the
insulators.
I had a cubical quad and could identify the offending pole and could
likewise null out the noise.
Oddly, I don't recall there being a problem on the 80m or 40m dipoles.
You could always do a quick noise check with a mobile HF rig or a handheld
AM shortwave receiver.

Subject: [Elecraft] [OT] Ham Radio near high voltage power lines?
Just moved to a new QTH and there are high voltage power lines cutting
across the corner of our property running NW direction. The house is on the
East side of the lines.
Is it reasonable to expect good operability or is it a wash? I don't want to
go through the troubles if I'll just be frustrated.
Was looking to do a 60' tower for the high bands (I'll still be below the
lines height wise), multiband vertical (low bands 80/40/30) , and
dipole(80/40).
Vertical is planned to have 60 or more radials.
Thanks in advance.
