7 Feeder Installation
Feeder is used to connect antenna with MSR2000. Due to the high
propagation loss for high frequency waves , the feeder must be as
short as possible to get minimum loss of signal strength. If long
feeder must to be used, higher diameter feeder is recommended.
The typical propagation loss of 100 meters is listed in the table
below:

Tools needed for feeder installation: adjustable Spanner, paper knife, Diagonal Pliers.
The procedure of feeder installation:
1 Connect feeder to antenna port. Fasten the connection by turning the feeder connector clockwise
slowly;
2 Further tighten the connector with spanner;
3 Cabling the feeder following the pole, and be careful of
the arrangement of cabling, and without any sharp band of
the cable.
The radius of cable bend should less than following figures of
different types

4 connect to the other side to lightning protector;
5 Secure the feeder on pole by black sheaf rope and
don’t hang the feeder in the air;
6 Airproof the connectors by insulating tape and PVC
