‘LONGRANGER’ HIGH PERFORMANCE ALL-WEATHER GSM ANTENNA

(GSM/GPRS/Cellular/3G)

Compact, penta-band antenna for use in weak signal areas and suitable for outdoor deployment from tropical to artic climates. It provides an external antenna option for the ‘ENDURANCE’ GSM/GPRS Modem System, or can be fitted to existing modem installations for improved communications. Very high quality, but competitively priced.

Standard product is supplied with 5 metres of low loss cable for high mounting. The standard product cable is terminated with an SMA connector but can be supplied with different types of modem connector including FME.

Supplied with a stainless steel ‘L’ bracket for wall mounting or can be bulkhead mounted. The N-female connector on the antenna base fits through a 16mm (5/8th inch) diameter hole and is held in place by a hex-nut and washer and an O-Ring creates a watertight seal.

The standard product is ground-plane-independent (NGP), meaning it must be mounted on a non-metal surface; optionally a ground-plane-required version (RGP) is available where mounting is to a metal surface.
