I am just curious if I make a coaxial dipole for 800 Mhz, is there any additional attenuation added by enclosing it inside a small PVC pipe to weatherproof it?
On the same topic, can you make two such coaxial dipoles, one for aircraft band, and one for 800 Mhz, and tie them together at the SO239 jack at the bottom? I notice some of the multiband half wave antennas use stubs for the different bands attached to a low band half wave, and was wondering if it would work to tie two coaxial dipoles for two different bands (three bands maybe) into one connector?
