Chapter 2: Site Preparation
Antenna Mounting Locations
The base station uses two antennas (main and diversity) per sector. Consult your SOMA Networks
technical representative for information about the size, weight, and installation requirements of the
antennas.
Cabling Requirements
Ensure that your site has the necessary cable racking to accommodate the base station and that your
site has external cable access ports for RF antenna cabling.
Ground Cable Fastening Techniques
Figure 2.1 shows the correct methods for fastening cable grounds to a master ground bar (MGB) (or
other suitable grounding point. SOMA Networks recommends that only one ground cable be fastened
to a ground stud. However, if circumstances require multiple connects to a single ground stud, the
grounds should be attached using the correct method shown in Figure 2.1. By using this method, the
ground from one rack can be removed without disturbing the ground for the other rack.
