Omni Antenna
The RFS Omni antenna is installed on a structure, such as a tower or a pole, which is defined in
the site survey and design. Following are the steps to complete the installation of the panel
antenna. Refer to the Regulatory Information in Chapter 1, Page 8 prior to installing.
Assemble the Antenna Mount per the instructions that come with it (Figure 43). Use a compass
to determine which direction is true East (incorporating declination angle - see Figure 31).
Position the Antenna Mount in a direction to provide accessibility to the RFS after it is installed.
Position and install the Antenna Mount on the mounting structure so that any one of the eight
mounting hole pins is facing East. Tighten the Antenna Mount hardware to secure it to the
structure (Figure 44).
Sweep the RFS antenna inputs for dB loss. Record all results for later calculations. Position the
RFS on the Antenna Mount, ensuring that the arrow on the bottom of the Antenna Mount faces
true East. Secure the RFS antenna to the Antenna Mount (Figure 45). Install surge protectors on
the 8 antenna and 1 cal connectors.
Connect the eight antenna cables, cal cable, and Data/Power cable to the RFS antenna. Attach the
ground wire to the ground stud. Install grounding kits from RF cables to buss bars. Sweep the
antenna and cables from the RF cable connectors that attach to the BTS. Record all
measurements. Weatherize all connections (Figure 46).
Verify Installed Circuit Cards
WARNING! Ensure that power to the BTS chassis is off before installing the
circuit cards or any of the RF Power Amplifiers in the chassis.
FUSES ARE NOT FIELD-REPLACEABLE. In case of need to replace a fuse on a CHP (F1),
CC (F33, F17-32), SYN (F3), MDM (F1) or PA (F1) contact Navini Networks Technical
Support
CAUTION! For continued protection against risk of fire, replace only with the
same type and rating of fuse.
ATTENTION! Pour ne pas compromettre la protection contre les risques
d’incendie, remplacer par un fusible du même type et des mêmes caractéristiques
nominales.
CAUTION! - Please contact Navini Technical support before attempting to
exchange cards between chassis of different type and frequency to verify
compatibility.
The circuit cards, including the RF/PA cards, normally come seated in the BTS chassis. If they
