Moved onto 3 rural acres about 14 yrs ago. Only had one (15') tree on
the whole property, AND I had sold my yagis and tower about five years
earlier. So I went with monoband GPs on 40-30-20-17-10.
All were 9-10 ft above ground and used 4 elevated radials.
I borrowed a used 4BTV, set it up with the included 24 radials on the
ground. Comparing it to my 20m GP showed the monoband GP to be 0.5-1.0
S-units better. So I convinced myself the 4 elevated #14 solid copper,
pvc jacketed radials were worth it.
A few years later I expanded the 40m and 20m GPs into 2 el phased
arrays, and the nice 3dB gain punches into Asia quite well. Plus the
fat forward and rear lobes give me about 300 degree useful coverage,
with a couple of nulls in between.
The only deer damage Ive had is to my SAL30 RX antenna which I only
put up 3-4 ft above grade.
(should have put it up 8 ft.).
Elevated radials work very well indeed.
OTOH, my 160/80m INV-L's share a common 26 radials that I roll up for
mowing season, and uncoil onto the ground for winter.
PS Built a home brew Moxon for 10m last year and it is a good notch or
two above a single GP.
Added a 3 el vert (Bobtail curtain) for 12 which is working well but
not at a Moxon level. Worked Bouvet with my 30m GP, and Bhutan the
year before. so the elevated radials are bringing in the rare ones.
