Product Description

The RMM-UMB-DN brings the wideband RMM-UMB electrical design directly to an N-male device or enclosure connection. It covers 750–1250 MHz and 1650–2700 MHz for legacy worldwide cellular equipment.

Direct equipment mounting: The N-female interface removes the one-foot cable used on the standard surface-mount configuration.

Range-dependent gain: Peak gain is 3 dBi in the lower range, 5 dBi from 1650–2000 MHz and 3 dBi from 2100–2700 MHz.

Example Model Configurations: RMM-UMB-DN-BLK
