The device has 4 antenna ports, 1 for each of the 3 sectors, and for 1 the GPS antenna. 
“Antenna 1” must be connected to the antenna pointing South of the tower, “Antenna 2” 
must be connected to the antenna pointing toward azimuth 60° and “Antenna 3” must be 
connected to the antenna pointing toward azimuth 300°. The GPS antenna port must be 
connected to a GPS antenna. The antenna ports are shown in Figure 

 
 

 

 

 

 
The impedance of the chassis mount BNC female connector is 50 Ohms. For proper 
operation of this device, this connector should be connected to a 50 ohms coaxial cable 
with BNC male connector. Any 50 ohms coaxial cable with male BNC connector on one 
end and antenna on the other end can be used. However, the recommended coaxial 
cable is LMR-900. The recommended antennas for 3 sectors are 900MHz 90° antennas 
vertical with gain no more than 6dBi. The antenna for the GPS is not necessary at this 
point. Additional details are included in xG’ Network Implementation guide. Please 
contact your xG sales representative for access to this document.  
 

Before turning ON the device, please connect the antennas using the 
recommended coaxial cable to the chassis mount BNC connectors installed on 
the rear of the unit. The cable and antenna acts like a load to the xMax BSN200-

3S. Never turn the unit ON without first installing the cable and antennas.
