50MHz 4-element Long Yagi
It's built with a round 32mm boom and 20mm elements, originally it was designed with it's own boom-to-mast attachment, but this turned out to be too weak, and I used one from an old Parabeam
50MHz Moxon Rectangle
The Moxon has been on my chimney for nearly nine months as of April 2007 through up to 50 MPH winds and some light icing with no problems
Antenna direttiva 3 elementi per 50 mhz
The boom is made up of a single piece in 20x20 aluminum with a length of 240 cm
70 MHz - 50-MHz reflector Hentenna
