Helical Antenna and Patch Antenna 5.8GHz FPV [Education]
posted June 17 2014 9:41.55 by spic0m




Oscar Liang writes about Helical and Patch antennas and their pros and cons:

"I think the most commonly used antenna for the 5.8Ghz FPV system at the moment, is the Cloverleaf antenna. Because it's onmi-directional which is suitable for most situations, and it's generally cheaper. Helical and Patch antenna are directional antenna. They provide longer range, but it does not do very well when you fly to the sides or behind it, the antenna has to face the copter or plane to get best performance."
