Gernic antenna, if it is within 3:1 vswr then it is matched fairly well.
Gain is directional, this one should have a pattern that changes as one
moves up in frequency, more lobes.
good one to check on on EZNEC (demo free on internet)
Low Freq need a good ground.
Also this type of antenna was used in the 20's and 30's, and on the ships at
sea.

The military is using these antennas because of ALE (automatic
linking) and NVIS. I gather that while they are very broad
banded, they have less the best gain?

Any feed back?
