The RFMAX RKD-44 series antenna is designed to replace a single 2G or 3G cellular antenna with a DUAL 4G/LTE antenna in the same 5/8 inch mounting hole. This unit is purpose built to be small (2x2x2 in.) ultra-rugged and tamper proof which makes it ideal for use in public places.  A VHB gasket seals the mounting location from water ingress, and 5/8 threaded mounting stud provides a completely vandal proof design.  As companies retrofit existing equipment to upgrade from 2G or 3G to 4G/LTE, this antenna offers a DROP-IN replacement from a single antenna to a MiMo (dual) 4G/LTE antenna.
