i.
While installing the antenna feeder system on a tower,
make sure the ground cable of grounding kit downwards
along the tower.
ii. While installing the antenna feeder system atop a building,
lead the ground cable of grounding kit towards a lightning
net.
3. Before installing the grounding kit, in order to enhance sealing
effect and avoid water into feeder inner along the ground ca-
ble, first wrap waterproof self-adhesive tape round the ground
cable close to a copper sheet, as shown in
F
IGURE
4. Clamp an outer conductor of feeder with a copper sheet of
ground cable and a snap spring and make the copper sheet
combined with the outer conductor.
5. Perform waterproof and sealed processing for junction between
ground kit and feeder. The methods are listed as follows:
i. First wrap waterproof self-adhesive tape and then wrap PVC
adhesive tape.
ii. For waterproof self-adhesive tape, first wrap from lower to
upper layer by layer, then wrap from upper to lower layer
by layer, and finally wrap from lower to upper layer by layer.
During wrapping, the former layer covers a half of the next
layer.
6. The grounding terminal of ground kit can be connected to a
body of tower or a cable tray on the top of building. . While
connecting, remove the paint and oxide at connection place
within a radius of 13 mm (8/16 inches) around the joint, and
daub the place with antioxidant cream to ensure good electric
contact. After connecting, paint the joint with anticorrosive
paint.
