Hi Joe,
I have "played" with a 3-el 6M LFA from Innovantennas. Seems to play just
fine although I have no way to check the true gain. It is very important to
keep the balun away from the boom -- see attached photo. (Photo won't go
through to TowerTalk.) Otherwise your SWR can be high.
Here are my SWR measurements with the yagi at 18' (yes -- too low for real
DX):
50.0 1.02 : 1
50.1 1.0 : 1
50.2 1.0 : 1
50.3 1.01 : 1
50.4 1.12 : 1
50.5 1.22 : 1
50.6 1.4 : 1

Subject: Re: [TowerTalk] OWL and LFA antennas
I've built a few LFAs for 6m, 4m and 2m. They all came in right on the
nose, and outperform anything I had before. They're extremely quiet on
receive, with a very clean pattern.
Good luck es vy 73

Does anyone have any first hand experience with these OWL and / or the
LFA type of beams? I am mostly interested in antennas for 6 and 2 meters.
I have been looking at antennas for what I feel is too long and I am
ready to get some more beautiful aluminum and stainless in the air to
punish the atmosphere.
I have heard that these type of antennas are not quite ready for prime
time, it has been said to me that they are very sensitive to the weather
changing S.W.R. if it rains or snows. I won’t stay up too late worrying
about snow here in Florida but it has rained here before.
I don’t mind at all trying something new but I don’t want to stick my
head into the noose if there is actual evidence saying that these type of
antennas are flawed in some really noticeable way that will make me
regret putting them up there.
Thank you for your help,
Joe N4JBK
