6-Element-28-Ohm-Yagi with 7.20m-Boom


Short data: Gain 10.1 dBd, F/B >20dB, bandwidth 1MHz (49.6-50.6 MHz) at SWR < 1.5. This Yagi was built first for 2m and  and the pattern was verified by measurement. After that the Yagi was scaled for the 6m-Band. I will use that Yagi in the next time 2m above of my 15-Ele.-Log-Periodic on a new tower.

The design is very uncritical and you can mount this Yagi 2m above another beam with very low detuning effects!
