TERMINATION OF WLAN RP-SMA CONNECTORS

1.  INTRODUCTION

We tried to solder the RP-SMA socket center onto the RG58 coax cable (shown below). Unfortunately, the center socket was crushed the first time the cable was connected to the WLAN AP.

RP-SMA connectors: Antenna extension cable to WLAN AP.

RP-SMA connectors: Antanna side.

2.  ANTENNA RG-58 EXTENSION CABLE

The following components are needed to make antenna extension cable of RG-58 type.

2.1  Connector that matches antenna

1. RP-SMA connector with outside threading and pin center, for RG-58C/U ø 4,95 mm coax cable:
   ELFA P/N: 46-451-80
   Termination details:

• Crimpning shield: 5,41 mm
• Crimpning center conductor: 1,32 mm
• A:13.1 B:2.5 C:8.3

2.2  Connector that matches WLAN Access Point

RP-SMA connector with inside threading and socket center, for RG-58 coax cable:
