Unique-Bargains RP-SMA Male to Female Antenna Cable RG174 4 ft 2pcs

SKU CH-FQP2-AZPMG

Two 4 ft RP-SMA male-to-female RG174 cables with 50 ohm impedance and 0.11 inch diameter extend wireless antennas for optimal router placement

  • Product typeHI - Antennas, Wires & Fittings
  • Extends wireless antenna up to 4 ft for optimal placement
  • Low-loss RG174 cable with pure copper conductor maintains signal quality
  • RP-SMA male to female connectors fit routers and adapters with removable antennas
  • 50 ohm impedance matches standard wireless equipment requirements
  • Pack includes two 4 ft cables for multiple device connections

Two-Pack RP-SMA Extension Cable

This pair of 4 ft RP-SMA male-to-female cables extends removable antennas on wireless routers, access points and adapters. Each cable uses RG174 construction with a pure copper centre conductor rated at 50 ohm impedance for low-loss signal transfer. The 0.11 inch diameter keeps routing flexible inside enclosures or along equipment racks. Both leads are terminated with standard RP-SMA connectors ready for immediate installation.

What the Pair Changes

Having two identical cables lets you reposition two antennas simultaneously or keep a spare on hand for a second device. The male-to-female layout preserves the original antenna orientation while adding 4 ft of reach per cable. Pure copper conductors and 50 ohm impedance maintain signal integrity across the extension so the router or adapter sees the same electrical length as a direct connection. No adapters or tools are required beyond the existing RP-SMA ports.

Capacity and Headroom

Each 4 ft lead comfortably covers desk-to-wall, shelf-to-ceiling or chassis-to-panel runs in typical home and small-office layouts. The RG174 gauge handles the 50 ohm Wi-Fi bands without measurable degradation at this length. Runs longer than 4 ft or installations needing outdoor-grade jacketing exceed what this cable is built for. Buyers needing plenum-rated sheathing, reverse-polarity SMA plugs or bulk spool lengths should look elsewhere.

Questions about this item

Does the RG174 cable itself degrade and need replacement?

RG174 coaxial cable is rated for indoor use; UV exposure or repeated sharp bending can degrade the jacket and increase loss over time, so inspect periodically and replace if the sheath cracks.

What limits signal quality first on a 4 ft run at 50 ohm?

At 4 ft the dominant limit is connector contact resistance and VSWR at each RP-SMA junction rather than cable attenuation, so keep connectors clean and firmly seated.

Does the cable or its connectors generate heat during continuous operation?

Passive coaxial cable and RP-SMA connectors dissipate negligible power at typical Wi-Fi transmit levels, so no measurable heat rise occurs during all-day use.
