I have built the AMRAD e-probe antenna but have yet to put it up somewhere.
I have read that it performs best the highest you can get it, and best
higher than anything else in the vicinity. How critical is this? I could
put it up alongside one side of my house, where it would be well away from
trees, etc. I can put it on a 20 foot pvc mast. The trouble right now is
that I need an extension ladder to get to the crest of the house roof and I
don't have one.
I could put it lower but wonder how well it will perform.
