Product Description

The RMM-UMB is a broadband antenna for 3G, UMTS and AWS equipment that must operate across regional frequency allocations. Its two supported ranges extend from 750–1250 MHz and 1650–2700 MHz.

Broad legacy-cellular coverage: Frequency-dependent gain reaches 5 dBi from 1650–2000 MHz and 3 dBi across the other stated ranges.

Surface-mount feed: A one-foot RG-58 pigtail terminates in an SMA male connector, and the mounting surface should provide the recommended ground plane.

Example Model Configurations: RMM-UMB-1C-BLK, RMM-UMB-3C-BLK-12
