higher voltage, but not real high-tension wires.

All other things being equal, am I better off:

1 - Putting this thing up parallel to, or more perpendicular to, the
powerlines?

2 - Having the coax meet the wire at the base of the tree and
grounding it there, or running the coax up the tree and then depending
on the outer braid on the coax for ground purposes? The coax is
grounded at the first termination point at my MFJ antenna phasing unit
using a short, heavy copper wire to a ground rod.

Gentlemen, Peter and Kevin, thank you for the excellent ideas - some I
knew, some ARE new - I don't have a lot of room to experiment, but my
trees are situated so as to allow a generally perpendicular
orientation to the power lines, my main nemesis. Unfortunately, 30
feet is about as high as I can practically put them, but it's higher
than what I have now, so anything is an improvement, eh? Again,
thanks :-)



You're welcome.

Scaling the inverted L I described to half size -- 30 feet vertical
and 45 feet horizontal -- will still give excellent performance.


73,


Kevin, WB4AIO.
