  • TypeHI - Antennas, Wires & Fittings
  • Extends antenna placement up to 20 ft for better signal
  • 50 ohm impedance matches standard wireless equipment
  • RG174 low-loss cable minimises signal degradation over distance
  • Pure copper conductor ensures reliable conductivity
  • RP-SMA male to female connectors fit removable router antennas

RP-SMA Extension Cable 20 ft

This RG174 antenna extension cable connects RP-SMA male to RP-SMA female, extending a wireless antenna up to 20 ft for optimal placement. It is designed for users who need to reposition a removable antenna on a router, access point or adapter. The 50 ohm impedance matches standard wireless LAN equipment.

Low-Loss RG174 Construction

The cable uses pure copper conductors to achieve very low signal loss over the full 20 ft run. A 0.11 inch diameter keeps the cable flexible for routing through tight spaces while maintaining the 50 ohm characteristic impedance. Performance remains stable under continuous transmit and receive cycles.

Replaces Short Factory Leads

This cable upgrades the short pigtail or fixed antenna lead supplied with many routers and adapters. The jump is worth it when the stock cable forces the antenna into a poor location behind metal or inside a cabinet. Buyers who need a different connector polarity or a length beyond 20 ft cannot use this product.

Questions about this item

How much signal loss should I expect from the 20 ft RG174 cable during continuous operation?

The RG174 construction is described as very low loss at 50 ohm impedance, designed to maintain signal integrity across the full 20 ft length.

My router has an RP-SMA female jack — will this cable connect directly without an adapter?

Yes, the RP-SMA male plug on one end mates with your router's RP-SMA female jack, while the RP-SMA female end accepts your existing antenna.

Can I use this extension with an older Wi-Fi adapter that uses a standard SMA connector?

No, RP-SMA and SMA have reversed polarity threading; this cable only works with RP-SMA male and RP-SMA female ports.
