This is a comparison between the Fatshark circular polarized antenna and circular polarized antenna from Aomway.
Both are RHCP.
In my opinion there is not much differents.
But just look at the video and make up you own mind ;-)
Both are 5.8Ghz
Please note the TX is not really good quality one (in normally use ImmersionRC 600mW) but it should not make much difference in this comparison.
