Introduction
The objective of this procedure is to install the RF Cabinet Remote
Global Positioning System receiver (RGPS) antenna cabling.
The cable between the RF Cabinet and the RGPS head is 22 AWG
12–conductor wire configured as six twisted pairs. Power for the RGPS
head is provided by the cabinet via the the 12–conductor cable.
This procedure assumes that the RGPS receiver has been
installed, and the cable routed to the BTS site. For
instructions to install the RGPS receiver see Appendix A.
