Does anyone know of a good design for a reasonably high gain
bidirectional antenna for a 440mhz video TX? I am putting a 4 watt A/V
TX in an RC plane that will fly on auto pilot directly away from the RX,
make a 180 degree turn and fly directly back. So to get the best range
I was thinking some kind of bidirectional yagi. Depending on element
spacing and how big of a plane I get, I can probably only have 3
elements maybe 5.
