You do say "racing drone" , racing drones are usually used for the very sport indoor and are high powered mini drone with very little aerodynamics ! , "meaning a giant high discharge rate battery" !
There were drones developed for sport that have a follow homing function, but to fly a racing drone near someone is heinous stupidity let alone the powerful bulk of a tiny racing drone , the equivalent of cutting into someone with a chainsaw for power and the bulk of throwing a solid rock at someone !!!

However, i've been into circular polarised antennas lately and found a home-made DIY FPV antenna for video streaming
this is apparently for drones...
