The Fan antenna by TruRC is a good omni-directional antenna for FPV. The "fan" design is a compromise of the "turbine" design. The building process is simplier keeping the cost down. The goal in mind when designing the antenna was to have the minimum amount of blades, yet retain maximum multi-path rejection in all direction and still have an excellent SWR match. Works great on both Rx and Tx.
