We wouldn't get signals from satellites otherwise. Actually, that begs the question "which planet is the real ground"? John KD5YI Reckon we could hang a dipole all the way from the earth to the moon? No. What gain would it have and what frequency would it resonate on, I wonder. Well, lessee... gain would be the same as any dipole, i.e. about 1.76dBi not considering resistive losses because you did not specify a conductor size. Resonant frequency would be ~.372 Hz. This does not include the "capacitive hats" of the earth and moon. 73, Ian. Where would "ground" be? 73, John |
