No, I don't. I specifically said I wasn't sure and I had heard - and I
checked commercial sites as well as amateur and this is what I came up with:
The discone antenna is a broadband unity gain (ZERO dB) antenna.
From the commercial sites I checked, it appears that one can expect the SWR
to vary up to 2.5:1 (usually under 2:1), which isn't particularly good at
all.
I was wrong (and did mention I wasn't sure as I haven't used them), but did
bother to check it out. For others, it is always a good idea to verify
information. Zero dB gain (well, one commercial site specified it as zero
dB compared to a dipole or 0 dBd). So, it is better than a dummy load, but
far superior antennas are available with omnidirectional coverage.

jim do you believe everything you read on the internet?

Perhaps we should all do a web search on the discone. My understanding
was
(and I am not particularly familiar with the discone, although I have
used
a
biconical - a biconical is to a discone what a dipole is to a
groundplane)
that gain increases with frequency (to a point). It might be possible
(and
I emphasize 'might') to achieve a 7dBi gain (although that sounds high
to
me) in the upper middle frequency range of the device. At 25 to 30 MHz,
it
would likely have a gain equal to or lower than a groundplane. Anyone
care
to do an internet search and see what they can report?

When will these guys learn?

7dB gain???
I suppose it could be 7dBdummyload, but it's not dBi or dBd which is
what
you'd naturally assume..
