If you're looking at a G5RV, look instead at a Skelton Cone. With your
current transmitter/tuner combo, it will go from 10 through 80 meters, and
in fact, naturally resonates somewhere in the 10/12 meter area. I haven't
run any models on it myself, but others have told me that it actually shows
gain on 40 and 75/80 meters. I don't have any e-files on it, but I can
snaily a drawing to you if you can't find any other info on it.

Of course, these are just my own opinions, and are based solely on emperical
performance observations. Your mileage may vary...

Hi Mike,

Skeleton Cone????

I presume you mean Discone. Either way, and as a vertical, this would
not work very well to enjoy that "paper gain." If it works at 80M
(which would mean it is roughly 50 feet tall covering 8000 sq feet -
about one large, or two small residential lots) would suggest its best
radiation advantage for 10M is straight up.

Even though Discones (or other broadband antennas) have wide matching
characterisitics, their actual radiation performance varies
considerable over that same span of frequency.

If you expect to find significant gain, you need the discone to be
significantly larger, with a significantly wide cone skirt. In other
words, something on the order of an HF Horn design.
