[TowerTalk] Compromise Vertical antenna ground system?

[Thor Hallen]

You may want to consider one of the "half-wave vertical dipoles" such as 
the Gap Titan or the Cushcraft R-8. These antennas do not depend on a 
quality ground system and can be elevated above ground to reduce the ground 
loss that any vertically polarized antenna has. The R-8 is not advertised 
to work on 80 meters but it does a respectable job with an antenna tuner. I 
have not had any problems driving mine with up to 500 watts PEP SSB or 250 
watts continuous. IMHO, the Butternut propaganda on grounding is 
technically wrong and misleading. This is easy to confirm with the EZNEC 
antenna simulation program.

Guys (and gals)

Another grounding question if you don't mind? I've read and completely 
agree
with those recommendations describing a quality ground system for a 
vertical
-- many wire radials at least 1/4 wave from the base of the antenna.

Well, my problem/question: I have very little room to run horizontal 
radials
from the base of a Butternut HF2V I'm thinking of installing on the
ground.....at the most 10-15' in some directions, which is a little shy of
1/4 for 80 meters!  Any suggestions for a compromises ground system that
will make the best of what I have to work with? Would more ground rods 
help?
More radials, even though they will be electrically short?

I really want to try a vertical on 80-40, but concerned the lack of a
properly installed ground-radial system will lead to too much signal loss!

Thanks in advanced.........../k6sdw
