What this cable does

This 20 ft RP-SMA extension cable connects a Wi-Fi router or wireless card to an external antenna. It uses a male RP-SMA plug on one end and a female RP-SMA jack on the other. The shielded construction helps preserve signal quality over the full length.

Shielding and signal integrity

The cable is fully shielded to reduce interference from nearby electronics. Black PVC jacketing protects the conductors during routing through walls or ceilings. No power supply or active components are required for operation.

Connector polarity matters

This cable only fits RP-SMA ports, which have a reversed centre pin compared to standard SMA. It will not mate with regular SMA antennas or devices. Verify your equipment uses RP-SMA before purchasing.

Questions about this item

How do I connect the RP-SMA male and female ends to my router and antenna, and which step is often missed?

Screw the RP-SMA male connector into the router or card jack, then attach the antenna to the RP-SMA female end; the step people miss is confirming the jack is reverse-polarity (no centre pin) before tightening.

What upkeep will this 20 ft shielded cable need over time?

Inspect the black jacket and both RP-SMA threads once a year for cracks, corrosion or moisture ingress; replace the cable if shielding continuity is lost or connectors feel loose.

What signal loss appears first when running this cable at its full 20 ft length?

Attenuation increases with frequency, so the highest Wi-Fi channels show measurable drop-off first; keep the run as short as practical for critical links.
