VA3NCD had the luxury of being able to install 2 50MHz 7el Yagis for
testing one against the other. One an M2 7el JHV, the other an
InnovAntennas 7el LFA-WOS. He points them to various beacons and
switches the antennas.
No need to explain which is the LFA and why the LFA Yagi is called THE
Low Noise Yagi!
“I’ve put this quick video together to demonstrate the difference in the noise level I’m getting while using the InnovAntennas’ 7 element LFA2, as compared to the other antenna I’m currently using. The ANT1 in the video is my old antenna, the ANT2 is the LFA2. Additionally, the LFA in testing is installed just about 10ft above the ground, in my backyard, for some rough tuning/testing.Towards the end of this video, there is some part of SSB contact recorded, with the local station coming significantly stronger on my old antenna, than it is on the LFA. That would likely be the fact the local station is almost exactly in the back of the LFA, some 20km E-NE from me.
Both the LFA and the old antenna are pointing S-SW during this test.
I’ve picked some weak signals, at the end of today’s band opening, as the benefit is best seen on such.
I only regret I wasn’t quick enough to make some recording of the LU/CX/VP8 that were nicely heard on the LFA, in a TEP earlier today, too.
Well, all I can say is that I wish I had met Justin (G0KSC) some 15 years earlier…
Would have been much more fun DX’ing on 6m…
Now, I have three more of those, and an H-frame,
and all required accessories already prepared, waiting for better timing to install the entire array, which I hope is coming soon.
Just wait for more videos then…”
