What would be a good (free space, 1 GHz) antenna to achieve
circular polarizarion with a nearly spherical coverage?

Thanks,

Sam



Hi Sam

If you want "half spherical" coverage for receiving a circularly
polarized
signal, a turnstile is probably the easiest to build.
If your requirements for sensitivity are more stringent than the
turnstile
provides, a quadrafilar helix is excellant circular polarization.

Hi Jerry,

Unfortunately I am looking for the full sphere :-(
