Vszerda SMA Male-Female RG174 Cable Pack

This two-pack of 3-foot RG174 coaxial cables provides standard SMA male-to-female connections for 50-ohm RF applications. Each cable extends a Wi-Fi, FPV, cellular or security-camera antenna so it can be positioned for better signal reception. The black jacket is flexible enough for tight routing inside enclosures or along equipment racks. Buyers who need reverse-polarity SMA or longer runs will not be served by this kit.

Replaces fixed or short factory antenna leads

Swapping a short fixed pigtail for these 3-foot jumpers lets you move the antenna away from noise sources or metal chassis without changing the connector type. The upgrade is worthwhile when the existing lead is too short to reach an optimal mounting spot or when the original cable shows wear. Installations that require bulkhead-mount or N-type interfaces cannot use these cables directly.

Low-loss RG174 maintains signal over the full length

The 50-ohm RG174 construction keeps attenuation low across the 3-foot span so Wi-Fi, LTE or FPV signals arrive at the radio with minimal degradation. Connectors are crimped and strain-relieved to survive repeated mating cycles in mobile or vibration-prone setups. Performance remains stable as long as the bend radius is respected and the connectors stay clean.

Questions about this item

What length and connector types does the 3ft RG174 cable use for mounting?

Each cable is 3ft long with a standard SMA male connector on one end and an SMA female connector on the other, using 50Ω RG174 coaxial cable.

How do I install the SMA male-to-female extension without damaging the connector?

Align the centre pin and threads carefully, then hand-tighten the SMA male plug into the device or antenna port; avoid using tools that can strip the fine threads.

When should I replace the RG174 jumper cables in the 2-pack?

Replace a cable if the SMA connectors become loose, corroded, or bent, or if the RG174 jacket shows cracks or kinks that increase signal loss.
