Northwest view of my antennas. On the top of the 12m Versatower the 2m/70cm omni antenna X-50N from DIAMOND is fixed.
Both of the bands, 2m and 70cm, can be operated simultaneously by using an indoor antenna duplexer.
The antenna gain is 4.5 dBi for 2m and 7.2 dBi for 70cm band.
Below the omni antenna the 3 element rotary yagi beam FB 33 from FRITZEL is doing his job. The antenna gain is 7.7dBi for 20m, 8.2 dBi for 15m and 9.2 dBi for 10m band.
The front-to-back ratio best values for the above mentioned bands are 18, 15 and 14 dB. The boom length is 5.0 m and the turning radius is 4.5m.
The legs of the 40m and 80m aerials are fixed parallel to the roof and the other legs right-angled down to a pole.
