Using the TrueRC Singularity 5.8 Antenna is easy. Just connect it to your FPV device via the SMA connector. Make sure the connection is tight for a stable signal. When flying your FPV drone, the antenna will help you get a clear and strong signal within the 5.5GHz - 6.0GHz frequency range. For best results, try to keep the antenna in an open space away from any large metal objects that could interfere with the signal. As for maintenance, the antenna is quite durable thanks to its impact - resistant polycarbonate casing. But still, avoid dropping it or subjecting it to hard impacts. If it gets dirty, you can gently wipe it with a soft, dry cloth. Don't use any harsh chemicals as they might damage the casing. And that's all you need to know to get the most out of your TrueRC Singularity 5.8 Antenna.
