And,  also experience a radiating efficiency,  both xmit and rcv
of about 4 to 5 dB more poor than a very simple 80 meter
doublet!!  I had exactly the above up out here:  a Gladiator
vertical with four elevated radials -- was a real bummer.
It is long gone,  and now use a 137 foot or so long doublet,
fed with open wire feed line,  line spaced about 4" with pvc
pipe insulators.  Works so much better!!

No more elevated verticals here.  If I ever put up another
vertical,  it will be ground mounted.  And have somewhere
between 60 and 80 radials,  then it will probably only be
1 or 2 dB poorer in performance than my doublet,  hi!!
