My fpv setup consists of immersionRC 600 mW tx, black pearl monitor / rx, IBCrazy bluebeam ultra whip antennas. The picture looks good, but is not perfect even when tx and rx are very close to each other. Is some "noise" in the picture normal? I'm just wondering if it could be better. I have ordered the immerscionRC Uno rx. I am curious to see if that will improve the picture clarity.
