[TowerTalk] Wires in trees - QST month

[W1JCW John]

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.
