ZXG10 iBSC Hardware Installation Guide
Note:
i. The GPS feeder shall be as short as possible to reduce the loss and lightning
induction.
ii. 1/4″Minimum radius is 40 mm for a feeder bend and the minimum radius is 76 mm
for the consecutive bends (less than 15 times). The minimum radius is 80 mm for
a 1/2" feeder bend and the minimum radius is 160 mm for the consecutive bends
(less than 15 times).
iii. The shield corrugated copper tube is relatively thin for the feeder, so you do not
trample the feeder on the field.

7.7 Installing the Grounding Clips
If the BSC is installed in a room, regardless of the position of GPS antenna, the GPS feeder
is grounded at a point. That is to say, the GPS feeder connects outdoor grounding busbar
within 1 m in front of the feeder window by using feeder grounding clip.
This section introduces the installation process of 1/4" and 1/2" feeder grounding clips.
