[TowerTalk] Towers/Antennas Near 138kV Transmission Lines

[Keith Dutson]

I know Larry.  He visited me at my QTH recently.  My antennas are located
about 1/4 mile from towers with 12 138KV lines.  Noise from these lines has
never been a problem since 1999 when my 150 foot tower went up.

BTW, when I last climbed to the top of my tower and stood on the top plate,
holding on to the mast, I was above the very tip of the power line towers.
So my sigs just go right over the top. <grin>

73, Keith NM5G

One QTH I had in England was about a mile from some 400kV lines. During damp
or misty weather (ie nearly all the time in England!), the noise from the
lines made operation on 160m or 80m almost impossible -
S9+++ on the transmit antenna. There was no actual
fault on the line - the noise came from all along it - and I presume the
problem was caused by corona. I would take a lot of persuading to get a
house that close to any EHV line again.

I find it whimsical that over here line noise seems to be mostly caused by
loose hardware on distribution lines and is generally worse in dry weather!
