Good day all, especially Chuck and Frank.
I recall someone in the US Navy once telling me about an antenna array
deployed over the surface of a saltwater lagoon. Guess that's about
as close as we could get to the perfect ground plane. There were
other problems associated with corrosion though.
Plots in the CRC Antenna handbook (Report 1255, Ottawa, Apr., 1974),
shows -3dB take-off angles of the order of 3 degrees at the lower
angle above 14 MHz or so for salt water. Somewhat better at lower
frequencies.
Best regards,
Duncan Baker.
