In this video I compare a range of 5.8GHz FPV antennas for RC model planes or multirotors or drones, and seen which produces the strongest signal as well as which has the best rejection of reflected signals (multipathing). The results are very surprising.
While the expensive antennas from Circular Wireless and ImmersionRC/Fatshark performed well, the Aomway skew-planar wheel gave the strongest signal and the uber-cheap Chinese antenna from SurveilZone gave the maximum rejection of reflected waves.
Another big surprise was the very poor performance of the Aomway 15dBi patch antenna which I can only assume was defective for some reason.
Not a surprise was the fact that the dual-band 2.4GHz/5.8GHz antenna was utter crap and hardly worked at all.
Once again, the helical antenna (naturally) gave the strongest signal, albeit at the cost of only having a 60-degree beam.
This video also very clearly demonstrates the almost total inability of the standard "rubber ducky" FPV antenna to cope with the reflected signals that cause multipath interference and dropouts.
Aside from the Aomway patch, the dual band antenna and the standard rubber ducky, any of these antennas will do a credible job on your FPV gear so choose according to your budget.
