Hee, hee. Bet you did not expect someone to report they had experience with underwater antennas, but I have been on an experimental project to put the Rogers "FLEX" Folded Conical Helical HF antenna on a submerged vessel. (Written up in IEEE Transactions on Antennas and Propagation)
Of course, it was not used while submerged. I also had some HF antennas on ocean buoys that wash over pretty regularly in a high sea, so it is operated underwater part of the time. Signal drops as you would expect. At 5 watts power, they were not going to work well when in washover. SWR goes crazy, but they right themselves pretty quick and that is what foldback SWR protection is for. Rig was FT 5 watter. -Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
