Install Cables
All cable connections in the Combo and Split-Chassis configurations are made using standard
RF coaxial cable. The Navini Networks minimum for cable connections from the GPS to the
BTS is LMR 400, 3/8-inch coaxial cable. Other types of cable that are comparable may be used.
These were determined under “Antenna Power & Cable Selection” (Appendix L) activities cited
earlier. The TTA configuration uses a composite cable containing nine RG-6 or RG-11
individual strands to replace the 8 RF cables, the Cal cable and the Power/Data cable (the signal
previously sent through the Power/Data cable is now sent through the center connector of the
individual RG-6 or RG-11 strands).
All Coaxial and Digital cables between the Digital and RF shelves are 60 inches in length.
Physical distance between Digital and RF shelves will always be less than the cable length.
