70cm-Longyagis

The elements have 10 mm, 8 mm or 6 mm diameter, because this is very uncritical and you get the expected datas! For the tuning let the radiator 2mm longer and cut for best SWR at 432 MHz

70Mhz-Yagis

The Yagis have 12,5-Ohm resistance use the DK7ZB-match with 2xlambda/4 50Ohm coax or 28-Ohm

7-Element-Yagis stacked for the 2m-Band

These yagis and groups were designed with YO7.23 from K6STI and checked with EZNEC from W7EL. With a gain of 14/17/20dBd

3 element yagi beam 50 MHZ

SWR regulation with harpin system

8 Element Wideband Yagi for 70-cm

It's a scaled down version of the 144 MHz ultra wideband yagi produced by Rutland Arrays. The antenna design was optimized for broadband performance using YAGIMAX software

#### Antenna Big wheel 432 Mhz

ROS,al max. 1,5 nella banda che va da 431,8 Mhz a 433,8 Mhz
