[TowerTalk] ANTENNA HEIGHT

[Edward Sylvester]

My opinion is that, at treetop level, you will be ok with a Steppir, as the take off angles will be high enough to miss the trees....But if you are well below (50' tower below 70' trees), you will signal will suffer some attenuation.  A quad won't suffer as much due to its closed circuit design.
   
  I have a Steppir, too but it's in the clear.  Best of luck.

  My 4L SteppIR is at treetop level - on a 55 foot tower. I've worked 307 
entities in about 4 years - SWR is flat across the bands, including 40, 
and 30M is about 1.5 or so to 1. A SteppIR will work wonders, and the 
tower height should of little impact.

Good luck!
