[time-nuts] Choke Ring Design for L1

[Peter Vince]

As I understand it, the GPS signals are circularly polarised, and so
surely reflections will reverse the sense of that polarisation such
that the antenna will be insensitive to them?  Maybe Warren's simple
pie dish is working by shielding the antenna from the true MULTI-path
reflections, and any direct SINGLE reflections it produces are ignored
due to the polarisation reversal?
