I have read articles on the web recently that mention the low NVIS type
antenna's.
I'm not sure if your familiar with the concept but here is a link that I've
used
http://www.hamuniverse.com/nvisbeam.htmlI kind of like the one they mention - the cloud warmer - it looks like a
neat concept.
I would think that if you are wanting to intentionally get a higher angle of
radiation for more regional / local stuff - (instead of that very low one
your vertical is producing) - this would be a pretty good candidate.
One thing that worried me however was ground losses (running QRP it matters)
with it being as low as it is. I think the reason this design above using
the director "element" beneath the main radiator is to minimize the ground
loss but I'm not sure. Just an idea..
Of course your monofiliment over the 50 ' limb wont come in handy on this
one... !
