Thanks. I have said earlier that I considered a discone (I also
considered a cage monopole but didn't mention it here) but those are
vertically polarized antennas and I'm pretty sure they're not good for
NVIS. Am I wrong?
I am also considering an array of inverted vees cut for selected
frequencies within the range, Something like that is likely to be much
better for NVIS.
Sorry if I seemed to fit all those names you called me... you say I'm
defeatist, one or two others here say I'm too optimistic. Can't please
everybody I guess. For the most part I do very much appreciate all the
help everyone has offered here, in a thread that has grown way beyond
anything I envisioned when I started it ... you guys are great. :-)
