Two thin black coaxial cables with SMA male and female connectors at each end

Vszerda

Vszerda 2-Pack SMA Male-Female Extension Cable 33ft RG174 50Ω

SKU CH-PF7Z-QS1GA

Two 33 ft RG174 SMA male-to-female cables extend Wi-Fi or cellular antennas with 50 Ω impedance

  • Extend Wi-Fi reach with 33 ft RG174 cable
  • Low-loss 50 Ω coax keeps signal strong
  • Standard SMA male-to-female fits common gear
  • Two cables included for multi-antenna setups
  • Flexible routing lets you position antenna for best gain

Two-Pack SMA Extension Cables for Wireless Antennas

This two-pack provides two 33ft RG174 coaxial cables with standard SMA male-to-female connectors. Each cable carries a 50Ω impedance rating for RF signal continuity. They are designed to relocate Wi-Fi, cellular, FPV or security-camera antennas to a position that improves reception. The cables are not suitable for TV antenna connections or reverse-polarity SMA ports.

Low-Loss RG174 Construction Minimises Signal

The RG174 coaxial dielectric keeps insertion loss low across the 33ft run so the antenna receives a stronger signal without adding active components. Passive operation means no power draw and no fan noise. The flexible jacket routes easily through walls, conduit or vehicle trim without kinking. Standard SMA threading ensures a secure, repeatable connection on compatible routers, hotspots and PCI cards.

Consistent Performance Over Extended Cable Runs

Under continuous transmit or receive duty the cable maintains its specified 50Ω impedance, preventing standing-wave buildup that would degrade link quality. The double-shield construction resists interference from nearby wiring or RF sources during sustained operation. Because the assembly is entirely passive, thermal drift does not affect attenuation characteristics. Users who require reverse-polarity SMA or longer single-run lengths will need a different cable type.

Questions about this item

How do I install the 33ft RG174 SMA male-to-female cable without degrading the 50Ω signal?

Route the cable away from sharp bends and power cords, hand-tighten each SMA connector until snug, and verify the centre pin seats fully — over-tightening or kinking the thin RG174 dielectric is the common mistake that raises loss.

What maintenance or replacement will the two 33ft RG174 cables need over time?

Inspect the SMA threads and centre pins for corrosion or loosening every few months; replace a cable if the jacket cracks, water ingress occurs, or measured insertion loss rises noticeably at your operating frequencies.
