Connecting the system cables
Connecting the antenna
Note: It is good practice to coat the threads of all connectors
with a small amount of a suitable waterproof marine
sealant prior to securing them.
To connect the antenna:
1. Remove the protective cap from the
RF1 connector.
2. Connect the RF cable to the RF
connector and secure it using a 13 mm
spanner. Take care not to overtighten the
nut, as this will damage the connector.
Note: The base plate connectors must be suitably protected
from water ingress when the antenna unit is installed on
an open structure, e.g. a tuna tower.
Connecting the ACU
CAUTION
In-line fuse
If you do not have a breaker fitted in the power
circuit, an in-line 5 A quick-blow fuse should be
fitted to the positive (brown) lead of the power
cable.
To connect the ACU:
1. Connect the RF cable from the RF1 connector on the
antenna to the
ANT RF1
connector on the rear of the ACU.
2. Connect a 3m RF cable from the ‘
RECEIVER
’ connector on
the rear of the ACU to ‘
RF
’ on the IRD.
3. Connect the power cable to the rear of the ACU.
4. Connect the power cable to the 12 V DC power source.
