Of course, a dipole at 7 feet will have near-vertical gain
over a G5RV at 50 feet. Near-vertical gain is NOT what the
majority of hams desire. Near-vertical gain is the antithesis
of DX.


I differ on that opinion. My 40M/80M operational preferences are
definitely for close-in communications, such as getting on the Noon-Time
net, various in-state 75M nets, and other "local" activities". The lower
noise factor of the NVIS antenna helps, too. Of course, its best to have
two antennas, one such as NVIS and another well placed dipole, for optimum
choice.


What are you disagreeing with? How much DX do you work with
your NVIS antenna? Do you really think the majority of hams
are only interested in local communications on HF?


Yes the majority of hams are indeed interested in Local HF communications
on 80 & 40. Something that will reliably commutate out to 300-400
miles.

When they think of DX they think 20 - 10 meters.

Those that are interested in DX on 80 meters are a very small minority.

They can get that from a 40 ft. high G5RV. No 7' high
NVIS dipole is needed. AND you can work DX on 20m-10m
with that 40 ft. high G5RV. I repeat, the majority of
hams are NOT interested *only* in local communications
on HF. A 7' high dipole is a poor performer on 20m-10m.

Cecil, since I started this thread with a comment on yours, in retrospect
I will admit what you say above is true! My comment applied to a small
particular group of operators on the lower bands (or is that higher bands?)

The top band is considered to be 160m so I assume "band" is
associated with wavelength, e.g. "160m band". So it appears
that higher bands = lower frequencies, but I could be wrong.
The IEEE Dictionary is no help. It thinks a "band" is a
track on a rotating memory device. :-)
