10dBi - 6 Element OWA Yagi Antenna for 2 Meter band plan
Ham Radio, Hobbies February 3rd, 2008
Here is a 6 element yagi my friend and I have built for experimenting with directional antenna. Theoritically the antenna has about 10dBi gain in its main lobe and a good Front-to-Back ratio, a perfect substitute if you don’t have means to get the popular V24 Silverthunder antenna.
