Installing a Coax Ground Kit to End of Ice Bridge
Install coax ground kits prior to the jumpers at or near the end of the coax ice bridge.
■
At a pad site, connect the ground leads to a CGB that will be connected to the equipment
BGR with two No. 2 AWG BTCW.
■
At a platform, connect the coax ground kits directly to the MGB if the site configuration
permits.
Attaching a Coax Ground Kit at GPS and WAN Antenna
If the GPS and WAN antennas are mounted on the monopole or antenna support structure,
attach a coax ground kit to the coax as close as possible to the antenna and connected to a small
CGB.
1. Ground the stand-off pipe mount with one No. 2 AWG BTCW exothermically welded to the
mast and connected to the CGB with a two-hole lug.
2. Connect the CGB to the tower BGR with one run of No. 2 AWG BTCW properly strapped or
otherwise secured to the tower to prevent movement in high winds.
3. Ground the GPS and WAN coax at the bottom of the tower (described in this procedure) and
end of the ice bridge (described in this procedure).
4. If the GPS and WAN antennas are mast mounted near the equipment or ice bridge, the coax
ground kits must be installed and connected to the CGB at the end of the ice bridge, the
EGB, or the MGB, whichever is more practical and provides the shortest and easiest path to
ground.
5. Ground the GPS and WAN masts by one No. 2 AWG BTCW directly to the BGR, ground
bar, or to another piece of properly grounded steel.
Grounding a Coax Ice Bridge
1. At each end of the cable bridge, bond the steel supporting structure for the waveguide bridge
to the BGR with a No. 2 AWG BTCW conductor.
2. Bond the waveguide bridge/cable tray to the grounded support structure or BGR using No. 2
AWG BTCW and exothermic welds at each end.
3. Bond each section of the waveguide bridge/cable tray together with plates of similar metal or
with No. 2 AWG BTCW or #2 AWG stranded insulated wire, bonding each section together
at each joint.
4. If buried coax runs from the antenna support structure are used rather than a coax bridge,
still install coax ground kits at the base of the antenna support structure and just prior to the
equipment jumpers.
