If you can get vertical antennas within 1/2 RF wavelength of the tide
line, you will outperform any dipole by many db's at low DX angles. I
used the longest MFJ telescopic whip and two tuned radials elevated 3'
on 3 dxpeditions and had a great signal seaward for 20 thru 10. One
pair of radials with banana plug jumpers around insulators for 3 bands
and the other set of radials for 2 bands. I put up two of these
verticals for faster band changes. I used a SteppIR CrankIR with one
radial for 40 and 80. See "Verticals on the Beach - Some Modeling
Results", QST June 2016.

I'm hoping to get to Belize to work ARRL DX CW contest this year and I'd like
to take my Elecraft KPA500/KAT500 and operate 500 watts. I will be at a friends
house and not next to the ocean so I'm thinking of getting a doublet up in the
air as far as I can on a fiberglass pole, feeding with 450 ohm ribbon and
tuning it on 10 thru 40 and maybe 80M.
The fiberglass pole won't take too much weight so I'd like to go as small as I
can on the wire. Any suggestions or input?
Thanks, Gary KT0A
