Building the gamma match for 3 Elements Yagi UHF 70cm 435Mhz
Just like the gamma match for our 5 Elements Yagi the construction technique for building the gamma match for the 3 Elements UHF Yagi are similar (tolerance level of 3% to 5% on measurements for building the gamma match is fine). The gamma tube for the 5 Elements UHF Yagi is exactly 4.5 cm. Please refer to the diagram for actual measurements. This yagi will give you a good coverage from 430Mhz to 445Mhz on single configuration @ 1:1 SWR on center frequency 435Mhz and about 2:1 SWR on band edges.
