6-Element-28-Ohm-Yagi with 7.20m-Boom
 |
Gain 10,24 dBd F/B 20 dB Great Bandwidth updated Data July 2009 |
 |
Short data: Gain 10.2 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 use that Yagi now 2,30m 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! The antenna was constructed to reach the "magic" 10dB gain.

The 6-El.-28-Ohm-DK7ZB-Yagi built by Ed, N5BLZ
With this antenna he made a 50MHz-EME-QSO with Larry, W7UIV Larry used a single 7-El.-28-Ohm-DK7ZB-Yagi!
A great success with the genious software of John Taylor, W1JT! |
