SMA / RP-SMA RF Adapter Connector Kit — 50Ω Brass, Gold-Plated

Product description

This adapter pack contains four straight RF coaxial adapters for converting between SMA and RP‑SMA connectors. Contents: RP‑SMA Female to SMA Female x1, RP‑SMA Male to SMA Female x1, RP‑SMA Male to SMA Male x1, RP‑SMA Female to SMA Male x1.

Each connector is made from brass and finished with gold plating on the contact surfaces to resist corrosion and ensure good electrical contact. The adapters are designed for 50 Ohm systems and are straight-style, matching standard RF cable and antenna terminations.

Typical uses include converting antenna connectors for Wi‑Fi devices, radio equipment, RF coaxial cables, extension leads and FPV drone setups that use SMA family fittings. They let you adapt between reverse‑polarity and standard SMA genders without reterminating cables.

Purchase includes a 30‑day replacement warranty and a satisfaction guarantee. If a piece arrives defective, contact customer support for a replacement or assistance.

Pros

  • Covers common SMA and RP‑SMA gender combinations
  • Gold‑plated contacts on brass body for reliable connectivity
  • Rated 50 Ω for standard RF applications

Cons

  • Not weatherproof — avoid prolonged outdoor exposure
  • No cable or protective caps included
  • Mixed genders can be confusing without labeling

VerdictA compact, practical kit for anyone who needs to bridge SMA and RP-SMA connections. The brass construction with gold plating and 50 Ω rating make these suitable for typical Wi‑Fi, radio and FPV applications. The four adapters cover the common gender combinations and are handy to keep in a toolbox when swapping antennas or adapting cables. They’re not weatherproof, so use them indoors or in protect
