Dual & Broadband Magnet Mount Version RM/RMM Series 4 Direct N Pole/Wall Version Adapter 

These antennas complement Mobile Mark’s broad line of antenna products for Cellular 3G applications. 

The RM3 Dual Band is a medium profile 3” H, (7.6 cm) antenna with performance of 3 & 5 dBi max (frequency dependent). A ground plane is required to maximize gain. The antenna radome consists of black ASA UV resistant plastic, with a metal base and threaded feed thru. 

The bottom of the RM series is outfitted with a gasket for complete sealing. A mounting nut is provided. Magnetic mount versions, MGRM-900/1900 allow use without drilling a hole. 

The RMM-UMB is a broadband version capable of simultaneous operation on worldwide bands from 750 MHz up to 2.7 GHz, with excellent response. A direct N version is also available along with the standard surface mount.
