[TowerTalk] trees and verticals

[Mike Ryan]

Rather than have to guy wire one of my two verticals at my qth, I stood one
up within the branches of a 20ft or so tall tree in front of my house. It
helps disguise it as well. It is an HF2V that kicks but. The last thing I
ever worried about was a little absorption on HF. If this were a VHF/UHF
vertical, that would be another story. On HF? I doubt there is a lot of
difference.  - Mike

Absolutely. My rule is simple -- do the best you can, then get on the 
air and have fun with it. And, when I'm not on the air, I'm still 
thinking about how I can improve my station and antenna farm. For me, 
the point is that EVERY qth presents a different set of problems and 
opportunities for antennas. The challenge is to figure out which of 
known good antenna types that CAN be rigged at that qth at reasonable 
cost, and without causing issues with the XYL, the neighbors, or the 
city, are likely to work the best.

That was my approach here. When I first moved here, I made a scaled 
drawing of the trees around my clearing, figured out the distances 
between various pairs of trees and the azimuth of a straight line 
between those that were far enough apart to support resonant dipoles. 
This took a lot of work with measuring tape and compass, and I used 
Autocad to make the drawing. But it really paid off.

Since then, I've helped at least a half dozen hams think about what to 
do with antennas for THEIR qth, and I enjoy doing the same thing on 
Field Day and county expeditions for the California QSO Party..
