These images are of the 4 Element Antenna I built for working Satellites with.
The original idea and dimensions were from a Design by G8GMU (Thank you Brian for giving me the idea).
However, on Brian’s Design it had both the 145Mhz and 435Mhz antenna on a single hand held boom.
I wanted 2 separate Antennas to mount on my rotator permanently so this is how I made mine.
Special Thanks Again go to M3PYG for Donating the aluminium rod used to make the Directors, and reflector.
Thanks again Tony.
I have Tested it on the Local 70cm Repeater while holding it vertical in my hand and it gives a S9 on the Radio.
