My constant pursuit of finding the best antenna for the drone got me to buy a bunch of these antennas. Initially I did not understand why the drone would lose its signal even before 300 metres.
Well I have decided to disassemble the antenna and the reason why is staring you in the face. Its made from tin foil and a bunch of wires
Bear in mind that I paid around £15 for each. If I remember correctly the antenna is rated as 8 dbi for 2.4ghz and 11 for 5.4ghz.
Stay clear of this junk
