HBR RP-SMA Male Connector for L-240 Cable, Solder Contact
Locally Stocked

RP-SMA connectors are designed to interface with reverse-polarised wireless transmitters such as WiFi access points. The RP-SMA Male connector has the conventional male hex nut, but using a female receptacle as the inner contact.

This Straight-bodied RP-SMA Male connector is designed for an ordinary crimp and solder attachment to LMR-240 and equivalent series braided coaxial cables.

Installation is very simple. After preparing the cable, the pin is soldered onto the centre conductor and outer body pushed over the top until the pin sits flush. A standard 6.48 mm (.255") hex die is used to crimp the ferrule.

Recommended Use

This RP-SMA Male coaxial connector has been designed to support an extended frequency range up to 6 GHz, ensuring compatibility with Sub-6 GHz wireless and 802.11ac/ax WiFi.

Cable Suitability

L-240, sometimes referred to as LMR-240, is a low loss coaxial cable with a medium sized 6.10 mm outer diameter. This series is without a doubt the most popular choice of RF cable, due to its efficient compromise between performance and cost. 

L-240 cable provides the flexibility and easy installation of a smaller diameter cable, with the low attenuation and shielding advantages of a larger cable. Unlike larger cables, L-240 can pass 5G and mmWave frequencies up to 31 GHz.

Pound-for-pound L-240 has the lowest loss of any Flexible cable with performance comparable to Semi-Rigid hard-line cables.
