4-Pack RP-SMA Antenna Extensions for Wi-Fi and FPV

This four-pack supplies RP-SMA male-to-female bulkhead cables that extend antenna connections on routers, access points, PCIe wireless cards and USB adapters. Each lead uses RG174 coaxial cable with 50 Ohm connectors and measures 1 metre in length. The bulkhead female end mounts through a panel for a secure external antenna point. Ideal for installers who need multiple identical jumpers in one purchase.

RG174 Coaxial Build with Bulkhead Mounting

The RG174 cable is thin and flexible, allowing neat routing inside enclosures, vehicle cabins or drone frames. RP-SMA male connectors feature a centre hole while the bulkhead females carry a centre pin; the reverse-polarity keying prevents accidental mating with standard SMA hardware. Panel mounting lets you fix the antenna base to a chassis, rack ear or vehicle bulkhead without stressing the radio module.

Replaces Short Fixed Antennas or Damaged Leads

Swapping a stubby rubber duck for a remotely mounted antenna improves signal path clearance in metal racks, trucks or carbon-fibre airframes. The kit is not suited for applications requiring lower-loss cable runs beyond the supplied length or for standard SMA equipment such as TV antennas. Buyers needing longer runs, different connector genders or non-RP-SMA interfaces should select alternative cable assemblies.

Questions about this item

What RP-SMA interface does the 50 Ohm RG174 cable use, and what frequency does it support in practice?

The cable uses RP-SMA Male to RP-SMA Female Bulkhead connectors rated at 50 Ohm and supports 5.8 GHz operation for WiFi, FPV, and wireless video links.

What panel cut-out and clearance does the RP-SMA Female Bulkhead connector need to mount?

The RP-SMA Female Bulkhead connector requires a standard panel hole for the threaded barrel and a flat or D-flat anti-rotation slot; allow enough depth behind the panel for the 1 m RG174 pigtail to bend without kinking.

How is the bulkhead cable installed, and which step do people get wrong?

Insert the RP-SMA Female Bulkhead through the panel hole, secure the supplied nut and washer from the rear, then attach the RP-SMA Male plug to the device; the common mistake is reversing the polarity by confusing the RP-SMA Male centre hole with the RP-SMA Female centre pin.
