Unique-Bargains RG174 Antenna Extension Cable RP-SMA Male to Female 30cm

SKU CH-510G-DC28C

RG174 coaxial extension cable with RP-SMA male-to-female connectors adds 30 cm of reach for router, booster or WLAN Wi-Fi antennas while keeping 50 Ohm impedance and low loss

  • Product typeHI - Antennas, Wires & Fittings
  • RG174 coaxial cable keeps high-frequency signal loss low
  • 30 cm length adds reach without excess slack
  • RP-SMA male-to-female connectors fit router and booster ports
  • 50 Ohm impedance matches standard antenna systems
  • Copper conductor with PVC jacket resists everyday wear

RG174 Antenna Extension Cable

The Unique-Bargains RG174 Antenna Extension Cable is a 30cm coaxial pigtail with RP-SMA male to female connectors. It is designed for router, booster and WLAN Wi-Fi antenna conversion tasks. The 50 Ohm impedance matches standard RF equipment for reliable signal transfer.

Low-Loss RG174 Construction

High-frequency low-loss RG174 coaxial cable reduces attenuation over the short run. Copper conductors and a 2.8mm PVC jacket maintain signal integrity while staying flexible. The adapter connects a phone or device to an external antenna for better reception in no-signal areas.

30cm Reach and 50 Ohm Match

The 30cm length provides a short, tidy link between equipment and antenna without excess cable clutter. It comfortably handles standard Wi-Fi and RF frequencies within the 50 Ohm specification. Runs out when longer cable runs or different connector types such as N-Type or BNC are required.

Questions about this item

Will the RG174 coaxial cable or RP-SMA connectors need periodic replacement?

The cable uses RG174 coaxial construction with copper conductors and PVC jacket rated for 50 Ohm impedance; under normal indoor use the assembly does not require scheduled replacement.

What is the first performance limit reached during continuous high-frequency use?

Insertion loss on the 30 cm RG174 run increases with frequency and becomes the limiting factor before connector wear or thermal effects appear.

Does the 2.8 mm diameter cable generate noticeable heat when run all day?

The passive coaxial pigtail carries only RF signal current, so it produces no measurable heat during continuous operation.
