Unique-Bargains Gold SMA Male to RP-SMA Female RG178 Coaxial Cable 50cm

SKU CH-V38Z-XDFJG

Gold SMA male to RP-SMA female RG178 coaxial cable, 50 cm long with 1.8 mm diameter and 50 ohm impedance

  • TypeHI - Antennas, Wires & Fittings
  • Connects SMA and RP-SMA devices with gold-plated 50 Ohm RG178 cable
  • 50 cm length and 1.8 mm diameter suit tight routing spaces
  • Light 10 g build reduces strain on ports and extends cable life
  • Gold connectors resist corrosion for reliable signal transfer over time
  • 6 ft flexible RG178 coax handles Wi-Fi, GPS and booster hookups

Flexible RG178 adapter cable

This 50 cm coaxial cable uses RG178 construction with a 1.8 mm outer diameter and 50 Ohm impedance. It terminates in a gold-plated SMA male connector on one end and an RP-SMA female connector on the other. The assembly weighs 10 g and is supplied as a single piece.

Suits Wi-Fi antenna swaps and GPS links

Builders who need to mate an SMA antenna port to an RP-SMA pigtail on routers, boosters or GPS receivers will find the correct gender reversal here. The thin RG178 jacket bends easily inside tight enclosures. Buyers who require a lower-loss cable for longer runs or higher transmit power should consider thicker coaxial types.

50 Ohm impedance matches common RF gear

The cable presents a 50 Ohm characteristic impedance, which matches the majority of Wi-Fi, cellular and GPS antenna interfaces. Mismatched impedance would cause reflected power and reduced range, so this specification is the primary check before purchase.

Questions about this item

Does the 50 cm length suit a router-to-antenna link?

The cable is 50 cm (1.6 feet) long with a 1.8 mm diameter, so it reaches between a router SMA port and an external RP-SMA antenna without excess slack.

What does the 50 Ω rating mean for my Wi-Fi signal?

The 50 Ω impedance matches standard Wi-Fi, GPS and cellular antennas, so the RG178 cable passes the signal with minimal reflection or loss.

How do the SMA male and RP-SMA female connectors differ in practice?

The SMA male has a centre pin and inside threads; the RP-SMA female has a centre socket and outside threads, letting you join a standard SMA device to a reverse-polarity antenna.
