On some of my wharf visits, I would attach a lug to the base of the hamsticks
with a long piece of braided copper wire soldered to it with metal washer and
other weights attached to the far end, thinking that I would increase the
saltwater ground coupling effect.
That really didn't pan out and
Don't forget to add a resistor, to avoid stadic building charge:
10Mohm or so

Soil conductivity plays a much bigger role than most of us realize and
the "over salt water" is the gold standard`. As noted by a few other
respondents radials are certainly helpful but for those of who live on
quartz plains (sand) far from the ocean the far field losses can not be

I only deploy it when needed. I’m lucky to be able to put antennas up at all so
they go up on contest weekend Fridays and come down on Monday. I do leave the
ground hanging over the side and lower it into the water as needed to be used
with the insulated back stay.
It’s a balancing act doing

In 1990 I was visiting Antigua (V2) for 2 weeks. I had a Butternut HF6V
with 160 coil and I mounted it on a 3' piece of copper pipe in a
secluded part of the beach near the rocks about 2' above the waterline,
with about 30 short radials attached to it.

Hi Ignacy -
There's little hope that a vertical antenna hundreds of miles
from salt water can ever close the gap with an antenna built over
a salt marsh or within about a wavelength of salt water.
The purpose of radials is reduce losses in the power transfer
between a feedline and a vertical
I run an 80' high vertical on 160M from my sailboat in the saltwater of Puget
Sound/Salish Sea near Seattle. After experimenting with a number of different
saltwater connections I've simplified it to a single piece of 1/2" dia. copper
pipe 10' long and tapped in the middle. I hang it
Do more radials on a 160m vertical bring more improvements than shown
by simulation?
Most simulations, e.g. by EZNEC, show that going above 32 radials on 160m
brings minimal improvement, say 1 db to 2 max. Even for low angle signals.
On the other hand, some really loud stations on 160m, that
If the antenna stands in the salt-water or if you have a short, low
impedance connection to the water, you don't need radials.
During the VK9WWI DXpedition to Willis Islets, we installed a vertical on a
sand spit that was covered by water most of the time. We had 12 radials of
various lengths a

I have heard your signal confidently and have called many times. But all

I have not heard stations from the U.S. (except K1KI and W1UE - very
quiet + QSB). There were no conditions.

I was operating /MM from St. Martin (FK88) and both the NA and EU stations
were weak. OK2CF, who is normally a solid S7 in FL was barely above the
noise. Conditions were either very poor or everybody was in the QRP
category. The only strong signals were form the Virgin Islands.

George,
I came on about 4 times during the night, but propagation this side of the
pond was really poor.
NA Stations that are normally over S9 were around S5 . . . so couldn't hear
weaker signals at all. Even Europeans weren't very strong.
I did mange to work 16 NA stations, including Colorado and
18 matches
