Review on 🔌 TP1603 Tupavco N-Male to N-Male Adapter: Surge Protector WiFi Antenna Coaxial Cable RF Converter - Lightning Protection Arrestor - Coax Suppressor - Ideal Wireless Network Connector 0-6GHz by Johnny Chambers

I believe this thing has variable impedance, but I don't have a $100,000 S-parameter test kit to prove it. What I do know is that when this cheap Chinese PoS clone is inserted into the antenna line, I can't receive anything above 750MHz. If an identical looking (how about!) spark gap from a well-known brand is substituted in their place, the same signals will pass easily. It has a central through pin to the central pin. It is open from the center pin to the body. 6GHz?!? Do not make me laugh. DO NOT BUY. I banged my head against the wall trying to figure out why my SDR software isn't working,
