Eddy and others,
Some posts have already eluded to proper operation of the Beverage antenna
NEAR salt water, etc. The key in all these reported applications is that
the soil/rock immediately underneath the Beverage wire that composes the
other half of the traveling wave transmission line and creates the signal
tilt so that it is detected in the antenna wire, is NOT saturated with the
salt water.
The soil/rock is enough of a poor conductor, with the highly conductive
material far enough away, to allow the principle upon which the Beverage
works to be in affect.
At XZ0A I installed all the operaional Beverages up on the higher ground of
the island and they worked superbly. As a test I installed one at seaside,
somewhat over the portion of the shore that was exposed at low tide.
Results??? It was a dummy load even though it was identical physically to a
properly operating one just a few hundred feet away.
We are in the process of planning all the TX and RX systems for the VP6DX
excursion. We believe that the short bushes growing on Ducie indicate that
there is a few feet of sand/soil that is watered by rain and is not
saturated by salt water. We are planning on Beverages being the primary RX
antenna in the arsenal, and that they will work correctly due to the less
conductive area over which the Beverages will be deployed. Wish us success,
because hearing is the key on the low bands in the subtropics.
