I have an interesting QTH, and am mulling over a new elevated HF
vertical. I have studied all the usual suspects on eHam etc and poured
over the Champion report on vertical antenna performance.
Unfortunately, it is now a little dated and Steve, K7LXC says no
follow-on work has been done. And, I have corresponded with a few of
My QTH can be seen here: http://www.rbogash.com/ham.html
I have a large expanse of saltwater extending 180 degrees in front of my
house, pointing at all the good places, which would make a vertical
really shine. And, I have a large 24 gage steel roof, which I think
would make a great ground plane, and, er, obviate the need for a tuned
radial system. I've already experimented a bit by putting a 20 meter
Hamstick in a mag mount on my roof. This antenna outperforms all my
other 20m antennas on rx and tx by a wide margin, and it's not even
tuned very well (more work ahead to fix that.). I figured my house roof
was way better than a car roof. I've worked the world with this little
baby, and figure if a little bit of antenna is good, then a BIG antenna
is even better!
I'm looking mostly at 10-15-20m, altho 40 would be OK too. My existing
G5RV and Long-wire do fine for me on 40 and 75 now, so I'm not looking
for a kick there at this time.
I've gotten emails from SteppIR and ZeroFive saying the metal roof would
beat any radial system hands down. Any comments on my roof antenna with
no radials? Should the antenna radial connection point be bonded to the
roof? And, does anyone have any experience with the ZeroFive
Multi-band 43 ft monster (tuner required.)?
Thanks in advance.
