[TowerTalk] Hustler 6-BTV installation

[Brian Alsop]

I'm not sure one would ever notice the tree effects on HF.  There are 
lots of other things (e.g., no balun at the feedpoint, feedline routing 
and objects in the near field, ground terrain variations ) that would 
probably be larger effects.

I had an commercial BC TV engineer relate to me a story of the 
importance of attenuation in "trees" for HDTV (UHF).  One station near 
the NC coast (beaming inland) made an argument that the long leaf pine 
needles were the right size to selectively attenuate their signal.  They 
managed to get a somewhat higher permitted power.  It would have been 
interesting to actually have a measurement of the effect.......
