If you fly an RC plane or multirotor using FPV and want to make your own FPV antennas then you may wish to use RG402 semi-rigid coaxial cable instead of the more common RG316.

EBay is the cheapest source for this cable and you have to make sure you buy matching SMA or RP-SMA solder-type connectors - the RG316 connectors will not fit.
