3 – MRU/ARU Cable Connections

Connect Coaxial Cable and Antenna
Only the MRU has an antenna port. The ARU transmits its signal through RF cable connected to both the
MRU and ARU.
1- Before connecting the coaxial cable from the antenna to the MRU, check the Voltage Standing Wave
Ratio (VSWR) value to ensure it is within specification using a SiteMaster or DTF meter. Check if the
return loss is greater than 15dB or the VSWR value is less than 1.5:1. If it isn’t, you may need to redo the
RF connections on the cable.
2- Connect the coaxial cables to the antenna port of the MRU. Make sure the antenna connector is
tightened properly and free of dirt and the debris.
NOTE
: The antenna connected to the MRU is only for in-building use.
