## **Surface Mount Micro WiFi, CBRS & 4.9 Public Safety** 

- Mounts easily to vehicle or fixed utility box with a small 9/16” mounting hole (14.3 mm) 

- Impressive 2.5 dBi gain in a thumb-sized radome 

MRM Body Mount Antenna 

The MRM Stud mount series are micro-antennas that provide gain and performance that is close to larger products. 

A variety of single and dual band models are available for different broadband data system for WiFi and CBRS applications. The MRMUMB model, for example, covers Private LTE networks on CBRS (Citizen Band Radio Service) at 3.5 GHz. 

The MRM antenna design is “thumb” sized, only 1.35” H x 1” D (34 mm x 25mm). These antennas have a 1/2” diameter stud (13 mm) for mounting on up to 3/8” thick surface (9.5mm). 

To mount the antenna, access to the underside of the body surface is required. A Hex mounting nut is also provided. 

The antennas are normally outfitted with 1 foot (305 mm) of RF-195 cable with an SMA Plug Reverse polarity connector. Jumper cables can be provided for completing a longer installation. 

Peak antenna gain performance is 2.5 dBi for the MRM Series. The antennas should be mounted on metal for best overall performance.
