[Lowfer] e-probe vs loop

[Garry Hess]

Alan,

Thanks for the comment.

Yes, the loop is a single, untuned turn, based on VE7SL's writeup at 
http://members.shaw.ca/ve7sl/loop.html.

I've seen others comment that above modest height the e-probe 
sensitivity stops improving. Thus, an ideal location might be a large 
open field with the bottom of the probe up only 15' or so. That would 
place the antenna well away from local man-made noise sources but not 
too many of us have large open fields handy, hi.

The bottom of my e-probe whip is currently about 35' AGL. That places it 
above everything but my 65' tower (a roof tower with triband HF beam and 
a couple of VHF antennas is close in level, but probably not really 
higher). I've thought about putting the e-probe at the top of the tower 
mast (~75') and may yet do that, but I'm not confident it would survive 
there for long. On the other hand I have a new winch for the tower so 
raising/lowering won't need Hercules any more, and replacing blown JFETs 
is easy, and cheap.
