Two black coaxial cables with RP-SMA male and bulkhead female connectors

AUTECH

AUTECH RP-SMA Male to Female RG316 1m 2-Pack

SKU CH-C104-GH2AY

Two RP-SMA male-to-female bulkhead cables, each 1 m long with RG316 coax, extend Wi-Fi antennas for routers, cameras or PCIe cards

  • TypeM.2 Wi-FI Adapter
  • Extend Wi-Fi antenna reach with 1 m RG316 coaxial cable
  • Two cables included for dual-antenna routers or separate devices
  • RP-SMA male to bulkhead female connectors fit M.2 Wi-Fi adapters
  • 50 Ω impedance matches router and camera RF ports
  • Low-loss RG316 cable supports 5.8 GHz FPV and surveillance links

RP-SMA extension pair for remote antennas

This two-pack provides 1m RG316 coaxial cables with RP-SMA male-to-female bulkhead connectors rated at 50 Ohm. They let you relocate Wi-Fi or 5.8GHz antennas away from routers, PCIe cards, IP cameras, FPV gear or industrial modems. The cables suit any device that uses the reverse-polarity SMA interface shown in the compatibility list.

Replaces short fixed leads on stock antennas

Swapping a short pigtail for these 40-inch extensions lets you mount antennas outside a metal chassis, on a vehicle roof or at a higher point for better line-of-sight. The jump is worth it when the existing cable cannot reach the desired location or when bulkhead mounting through a panel is required. They do not add gain; they only move the radiator.

RG316 holds signal over the 1m run

The double-shielded RG316 construction keeps insertion loss low at 5.8GHz so sustained throughput on 5GHz links remains stable. Connectors stay tight under vibration in truck, RV or drone installations. The pair gives a spare for a second antenna port or a future device without needing another order.

Questions about this item

What panel hole size does the RP-SMA female bulkhead connector need for mounting?

The RP-SMA female bulkhead connector fits a standard panel cut-out for 50 Ohm bulkhead mounts; the RG316 cable is 1 m / 3.3 feet / 40 inch long and the pack includes two cables.

How do I attach the cables to a Mini PCI Express wireless card, and what mistake should I avoid?

Screw the RP-SMA male end onto the card’s RP-SMA female jack and the bulkhead female end through the chassis panel; do not confuse RP-SMA with standard SMA — the male has a centre hole, the female a centre pin.

When should I consider replacing the RG316 coaxial cables in a permanent installation?

Replace the cables if the RG316 jacket shows cracking, the connectors become loose or corroded, or signal loss increases on 5.8 GHz links such as FPV or long-range Wi-Fi.
