Feeder Installation
Feeder is used to connect antenna with MSR4K44S.
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

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 insulating tape.
