Picked them up with an SDR receiver to help pass the time in quarantine. Only one is needed, but a spare is always on hand. The packaging was easy to open and all mounting hardware was included. So far they are working or at least not having an adverse effect on the signal strength of my antenna. I'll admit I'm new to the wild world of radios, but in terms of quality at this price point, I think Bingfu will get more bang for my buck in the near future.
