Which one is the best antenna?

@Bill2002

geckoVN your hint because of losses 6dB is wrong in that case I do not understand from which source you have this or you do not understand the problem

Apologies - it’s 3dB

@Bill2002

if you till your vertical polarized receiving antenna 90 degrees you have a total polarization mismatch and you will receive nothin

Yeah, the maths says so, but have you ever tried it? Have you ever used an HT and actually tried it?

@Bill2002

So in worst case if the plane is flying a sharp u-turn you will have a total polarization mismatch and you will receive nothing with a vertically polarized Rod antenna…

I see no difference between a plane doing a U-turn and a plane flying past your location (in terms of the angle change presented to your antenna).

FAA Survey Flight?

Maybe checking to see if I’m flying my drone over 400 feet? [asf]
