This photo is of the barge over the Tektite II habitat; Summer 1970.
I operated W2YRQ from inside the habitat with a Hy Gain 14 AVQ attached to
this steel barge.
We also dropped some heavy cable in the water with the conductors unwound.
Worked great.

A 6" square plate makes an adequate ground when immersed in salt sea
water. That is unless the transmitter power exceeds 10 kW.
