I have a P2 with iOSD, gopro 4 silver, zenmuse h3-3d, and a AVL5.8 vtx. I recently bought a black pearl off of craigslist and am having problems with it. The monitor came with one of the stock antennas and one Immersion 5..8 spironet antennas. It took some channel searching to begin with to get a clear picture which wasn't too surprising, after 5 minutes of checking all the bands and channels, the clearest image was still pretty noisy and was quickly shifting. It was still better than flying without any screen so I decided to take my phantom for a spin, as soon as I armed the quad, the picture quality got even worse. Taking it up into the air I lost color, and flying it about 10 feet away I lost the gopro feed completely but still had the telemetry. Could the problem be that I don't have matching antennas?
