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 short yagis, i e yagis without side loobs. However I guess my point was to point out that the gamma match isn´t a totaly unusable thing, it didn´t seem fair to ditch it compleatly. I still consider it to be a very quick and simple way to feed a yagi antenna. I have 12 HF yagis with gammas, some over 20 years old, never had a problem. Also friends in the area got gamma matched yagis and we never seen those problems you guys line up. But as I did say previously, these days I probably would do T-match yagis instead since a gamma match isn´t a perfectly balanced feed. 73 Jim SM2EKM --------------------- Frank Donovan wrote: I've used gamma-matched Yagis for many years. I still have three gamma-matched 20 meter Yagis and my remaining 18 Yagis are T-match fed. All have been trouble-free for over 10 years. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
