Brilliant antenna better than the stock whip I use them for both transmitter and receiver and they work perfect I recommend making them stronger by wrapping a little insulating tape around the cable and then covering in heatshrink and putting a blob of epoxy over the centre of the tip of the antenna this makes them incredibly strong and pretty crash resistant.You will probably need an adaptor to convert it to SMAHoly wow these antennas are bad. I wondered at the price if they could be any good but figured it wasn't much of a risk. Instead I ended up with 2 completely unusable antennas. These are SIGNIFICANTLY worse than the standard whips that my fpv gear came with and my home-built cloverleafs which I thought were weak and was hoping to replace. I can't put my finger on why they are so bad either. Specs and angles look good, build quality seems decent. However, I was doing some range testing in the house and was losing signal within 20ft... how is that even possible?!!
