RF GPS Cabling (if applicable)
The objective of this procedure is to install the RF GPS antenna cabling.
Materials Needed
Table 5-11 lists the quantity and description of the necessary materials.
Table 5-11: Materials Required for RF GPS Cabling
Cable Part Number Description
J
Supplied in Kit
STAN4000A
RF GPS Cable, 1/2 inch coaxial, length=50 ft. Two male N–type connectors,
one end loose (to be field terminated after routing of cable through I/O boot).
If lengths greater than 50 ft. are required, cable style and length should be
determined by site configurations. Maximum loss <4.5 dB @ 1575 MHz for all
cabling and connections between the GPS antenna and the RF Cabinet.
NOTE
A 1/2 inch cable “pigtail” should always be used to exit the cabinet before
transitioning to a larger cable. This will ensure a proper seal at the rubber I/O
boot. It is suggested that the supplier cable be cut to the desired length to
achieve this.
RF GPS Cabling
Procedure
Follow the procedures in Table 5-12 to install the RF GPS cabling.
Table 5-12: RF GPS Cable Install Procedure
Step Action
1 Route the conduit (if applicable) for the cable (J) to the I/O area of the RF Cabinet. Refer to Figure 5-1
for recommended location.
NOTE
This step is omitted if the conduits is already in place in the concrete pad.
2 Route loose end of cable (J) from RFGPS Antenna through the previously installed conduit (if
applicable) and through the rubber boot in the floor of the I/O area (See Figure 5-6).
NOTE
The rubber boot is sized to seal a cable with an outer diameter of either 1/4” or 1/2”, if a different
sized cable is used heat/cold shrink or other means may be required to ensure a good seal. A tie wrap
or hose clamp must be used to ensure a good seal around the cables at the boot.
3 Terminate the loose male N–type connector to the loose end of the cable, and connect to RFGPS N
connector (see Figure 5-1).
