![]() I find this a little less time consuming and a little easier to get the geometry correct. One uses a protoboard as a substrate, the other simply uses the coaxial cable. I prefer 12 and 14 AWG because it is stiff. You can use just about any gauge wire you like. For this, I am using 14AWG wire to make an antenna for 910 MHz. It can have anywhere from 3 to 8 ¼ wave elements. However the counterpoise is very different this time. It has a single ¼ wave driven element and a counterpoise. This is a great solution so long as you don’t need to bank hard. ![]() ![]() Thomas Scherrer flies this antenna on his FPV plane mounted upside down. While I find it more useful on the RX side (preferring the Vee on the TX), some may find this an excellent antenna for ground vehicles. Range will increase slightly, but the real advantage is signal strength improvement at altitude. This actually increases the effective gain of the antenna. The ground plane antenna has multiple grounded elements that effectively drive the propagation pattern back upward. One solution to this is the ground plane antenna. Dipoles work ok, but almost half of the radiation pattern is into the ground and there is a huge hole above it. One of the largest problems I have had with FPV is finding a good omni directional receiver solution.
