    Nice, but that’s not a 15 degree beamwidth antenna. It’s a logperiodic antenna, and its beamwidth is tipically 40 degree with a 10dBi gain aprox (although it’s not so important, but I had to say it 😉

    Hi, show me the circuit schematics.
    Also you need to have the function RTH when RC fails in the phantom selected to control the drone, dont you ?
