Well, not quite I think. I think it´s one LC network for CW part of band and one for SSB part. W7EL network doesn´t have enough bandwith to cover 3500-3900 kHz, you need to use two LC net
Interesting Tom but it doesn´t adress what I wrote under this subject. Guess somehow things got mixed up. 73 Jim SM2EKM -- Tom Rauch wrote: power is carried in the feedline. In an ideal system,
I did my 80m 4 square more then 20 years ago. At that time there was no Comtek box to buy, it wasn´t invented yet. All there was was Mr Comtek (then KF4HK I think) and we used to work each othe

Improved in what way? Did a quick check in NEC. When going to about 1.5 wl spaceing, that will give about 2 wl on the diagonal, two strong aditional back loobes comes up in low elevation. Hardly does
Now I see my error. I checked at .35 wl spacing and that will give about .5 wl on the diagonal. Don´t know why I wrote 1.5 wl and 2 wl below, my fingers are to fast for my brain. Anyway, at .35
Strange. I´ve used gamma matched yagis for 35 years or so and also used (at times) very high power, never had a failure or any problem with it. Sure a gamma match isn´t a perfectly balanc

Agree, as I wrote in a previous post T-match sure is a lot better from a engineering standpoint. On a performance basis I dont think anyone can see any difference at least not when it´s up to s

What is a "parasitic 4 square"? As far as I know there is no "parasitic" with a 4 square since it´s a driven array. Did I miss something new?? 73 SM2EKM -- _____________________________________
This is probably the culprit. I have had elements fall off my Yagis before I did learn how to do tapering right, when tapering is right no ropes will be needed inside elements. In the Titanex case yo
