The impedance of the chassis mount BNC female connector is 50 Ohms. For proper
operation of this device, this connector is connected to a 50 ohms coaxial cable with BNC
male connector. Any 50 ohms coaxial cable with female BNC connector on one end and
antenna on the other end can be used. However, the recommended coaxial cable is LMR-
900. The recommended antenna for this unit is 902-928MHz omni-directional antenna
with either gain ranging from unity to 6dBi.
Before turning ON the device, please connect the antenna using the recommended
coaxial cable to the chassis mount BNC connector installed on the rear of the unit. The
cable and antenna acts like a load to the xMax VOIP BTS. Never turn the unit ON
without installing the cable and antenna.
