I'd like to read whatever information (real results) you guys have on this.
My email is my call sign with @hawaii.rr.com
Thank you Milt for your info. Nice setup! If I understood it correctly -
the buried and elevated were comparable.
I've read most of the well known books on this and it's not conclusive.. after
all these years - I would expect it be more certain.
I don't think the data is getting out there perhaps or I haven't seen it. A
study done working with low band grounding etc...
Things like
1) If you have the space and work hours and money isn't an issue - go with 120
1/4 wave buried radials.
2) Good soil doesn't require as many radials.. someone was commenting on the
AM towers be reconditioned - using elevated radials.
3) Elevated radials work better with poor ground conditions. Higher with
lower bands.. 15-25ft on 160m..
4) You don't need as many elevated radials as ground radial.. (debate about 4
to 12 or so?) I'd say 12 but would like to see a study. Some say 2 or 4?
Once you have the control antenna it's easy to start comparing real world
results. How's 12 radials sound? Cut 4 off.. how's 8 sounds. The
K.I.S.S. approach.
I don't think it would be very hard to disconnect some radials and say - "how's
the signal now?"... two guys with a walkie talkie making doing some tests
cutting some wires etc...
During the 160M SSB there was a guy in CA who was 59 the whole time into
Hawaii. I called him back on the last day and asked what he was using.. I
forgot what he said, but he switched his antennas and he went from a solid S9
to S5. He said that sounds about right. That was a huge difference.
I was using a 160m dipole up about 30ft at the center and 10 feet on the ends.
I'm sure that wouldn't model very well but I was 56 to him. I do need to
model in my sloping terrain to ocean etc..
That poorly modeled dipole that would be shooting up 90 degrees or something
can go 5000+ miles.
That's what I'm talking about. Why bother with a ton of wires and work
unless you can see a real world difference. I'm putting in an inverted L
with the FCP ground to see how that compares to my low dipole (radials are hard
for me)
My results will be based on - "Jack (W2XX), let me switch my antenna and tell
me how you copy me." If it's not a noticeable difference I might want use
that extra coax connection for something else later.
