High Gain Multiband Antenna
Fringe 4G · Security · Rural IoT
— Application
The DG900MB-HG is the antenna to reach for when a site sits at the edge of coverage. Its 7 dBi of gain from 700 to 1000 MHz recovers links that a standard antenna cannot hold, whether on a regional alarm panel, a base station or a vehicle. The element sits in a 45 cm fibreglass radome on a 12.7 mm stud, with FME, SMA, BNC or TNC on 2.5 m, 5 m or 10 m of low loss ALSR195.
