Colleagues,
On the strength of Jon's report below and several before and since,
please QRX with the survey until this glitch is ironed out. (The several
entries to the site before release were smooth, including mine, so this
is an unwelcome surprise. Never happened to me before during my

My TS-940 has the same setup but not the TS-950SD and many other rigs. I use
a toggle switch an high isolation DIP relay to do the control, under $5 in
parts.

It depends.. I think George describes the situations well.

phased.
He is on the rocky ground, close to salt water bay.
The best Beverage (most of the time) was the long one, going over rocky terrain

Well base loading should be better then linear loading, lower
losses. However the base loading LC network has to have low Q
or at least "decent" Q.
Once I had my 160 vertical linear loaded, it was a 90 foot
radiator. I did measure the difference between linear loading
and base LC network loading.
Mike,
It is not that they are near an ocean. It is if the conductivity of the
salt water is near enough under the beverage element such that the salt
water (or salted earth ie. salt marsh) is acting as the other conductor of
the "twin lead" transmission line (the Bev wire is one conductor in t
I think it is high ground conductivity that is often true of soil near the
ocean, not the ocean per se.

I think BCB DXers have used them on the coast many times with great results.
From what I recall about beverage antenna theory, there may be a problem if the
earth underneath is too highly conductive -- i.e., if the antenna is laid out
over a salt marsh.

Mike,
Here is the definite answer: it depends.
I have built a number of Beverages near the sea, with
varying results. On VK9WWI (Willis Islets)
