So far I have built two of these yagis for the 2 metre band using this style of gamma match, This basic 5 element design is from the ARRL Handbook and VHF manual. The first yagi I built in 1985 and it's long gone now. I've also built a 4 element 6 metre band yagi using the same style of gamma match. The gamma match uses standard 'N' type co-axial connector fitting and a piece of RG-213 co-axial cable. Once tuned it is sealed with self amalgamating tape and Silicon compound. An Anritsu Antenna Analyser was used to tune the antenna. Click on the images for a larger view of the image.
