Subject: [TowerTalk] Wires in trees - QST month
What month is the article in QST?
I've had many dipoles through tree usually for support and they worked well
and I worked lots of Dx.
Never had any arcing or fires.
Looked I had an RF issue last installation 230 OCF over trees at 40' and
when increased power swr was erratic.
Had 450 ladder line, down to 4:1 balun even tried coax at the feed point
with a wound choke same issue.
A good portion of the antenna went over the top of trees.

trees have on antennas in/near trees.

This is a topic that I have never seen addressed and Google has not
revealed any similar situations:
I am installing a quarter wave, 160m inverted-L between a 40'
Ponderosa Pine and my tower. The first 30' of the antenna will run
parallel to the tree trunk and through the branches. I am using copper
coated wire for the element. I have four elevated radials at the 10'
level.
My concern is whether I need to worry about contact between the wire
and the tree. With the very low humidity that we get during Colorado
summers, I am wondering if there is a fire danger here.
I will be running a 1.5 kW.
Thanks,
