[UK-CONTEST] Vertical over salt water

["Carsten Steinhöfel"]

Ken,

Use radials as normal, the salt water is only relevant for the far field. For the vertical to radiate properly it still needs radials. As ZK1EFD I have used 24 radials of about 10m each (some variation - not all equal) with a HF9V which worked well on 40-10 (80 matched but I couldn't get much DX).

Also I'd try to get closer to the water's edge. 100ft is several wavelengths on the higher bands. There was an article somewhere that concluded you should be less than half a wavelength from the water ideally if I remember correctly.
