A counterpoise is what we do when the full size of a double-ended antenna,
dipole, OCF, etc is too large for us to build, maintain, etc. Very simply,
we want to jam the energy from the shield of our coax into the
counterpoise, and the energy from the center conductor into the radiating
element,
Recycling signals at the feedpoint sounds more like a mismatch swr
situation.
The ground radials form half of the antenna, and that radiation from
ground, in phase with the vertical radiation determines the field
strength and take off angle.

I feel it more appropriate to say that the function of ground-mounted radials
is to harvest the radiation from a vertical antenna that splashes on the ground
and return it to the feed point for recycling.

Thanks to all who responded
I received a lot of good advice and will be taking it. Specifically, the
advice to bury the hardline rather than elevate it.

Now for 2 weeks my QTH hears a static-like S9+ noise on 160m, 80, and to a
less extent, 40m. No static heard on 30-10m. Makes 160/80m bands useless.
Beverages and 4 sq point to the East.
Seems the static is just within the ground wave of 40m but beyond that of
30m. Does anyone know the extent of
If the radials have a good chance be being submerged in fresh water, I would
consider elevating the radials.
Had an experience here where my 40 radials on each of my 4 square verticals
were often times below the water level and radiation efficiency dropped like a
rock. Great receive
What's the perceived problem with the cable being submerged?

Yes, conditions seemed good on Saturday night . . . I didn't realise there
was a Contest.
I popped on for about an hour . . . didn't put out any CQ calls, as I didn't
want loads of EU stations calling me. But I did work a few DX stations I
heard, a few NA stations, Caribbean, plus the guy in
10 matches
