Radio antennas are usually designed to work best over just a small range of frequencies so I was interested to see what was inside this dual-band FPV antenna from RCTimer. I have to say, it looks quite poorly made, lacking much in the way of the precision required to get good performance at these higher frequencies.
However, I will reserve my final judgment until I have actually tested the performance against the other omnidirectional CP antennas I have here for review
