Frequently Asked Questions
SMA or RP-SMA?
Consumer WiFi gear usually uses RP-SMA; cellular modems usually use standard SMA. Check the centre pin: SMA male has a pin, RP-SMA male has a socket.
Does a longer pigtail hurt signal?
Yes — thin RG174 loses ~1 dB per metre at WiFi bands; keep pigtails short or use lower-loss cable.
