Hey guys, I bought a second-hand phantom 3 standard, and I've been looking around to try to figure out what antenna the previous owner installed on the remote. I can see that the upgrade kit they used was BlueProton. However, there is an additional antenna, shown here, and I cannot figure out what the blue antenna is. The reason I'm looking into this is because I have had really poor signal and I'm not sure if it's due to this other antenna. Any help would be greatly appreciated.
