What would it use as a ground plane? Then, if it is (say) oriented along the line of flight, what if the transmitter is perpendicular to that. You will suffer a 10 dB loss of signal, or more. | |
Jul 3, 2015 at 11:16 | comment | added | AndrejaKo | There's one thing I don't understand here: Why would a properly attached whip be any worse than a dipole? If we could attach a whip to the bottom of an airplane, wouldn't its whole radiation pattern be pointed downwards, at our targets? If the UAV is helicopter-shaped, then this might be an even smaller issue. | |
