12 Pathfinder Radar Scanners
If you are mounting the scanner on the mast of a sailboat, and will
need to unstep the mast, you should install a suitable junction box
inside the boat.
On a radome scanner, the junction box should provide an 11- or 13-
way terminal strip, depending on the number of power cores in your
cable, with a 10 A rating. Also, you should keep the length of the un-
screened coaxial cores to less than 30 mm to maintain EMC
conformance.
On an open array scanner, the junction box should provide a 13-way
terminal strip with a 20 A rating for power cores. It is essential that all
4 power cores are connected and that the connection is of very low
resistance as considerable power passes through this connection.
Also, you should keep the length of the un-screened coaxial cores to
less than 30 mm to maintain EMC conformance.
Inter-unit cable
The inter-unit cable entrance is at the rear of the scanner unit. If the
unit is mounted on a hollow mast the cable may be run inside the mast
and then fed through the radar’s cable entrance. Make sure that the
cable does not chafe where it enters and exits the mast.
The inter-unit cable, for connecting the scanner to the display unit,
depends on your scanner package. Details are given in Table 1-1 and
Table 1-2 on page 4.
Note: Route the cable from the display up to the scanner, since this
will require the smallest clearance hole.
CAUTION:
The display connector on the inter-unit cable is a moulded plug
that cannot be replaced. DO NOT remove this moulded plug.
The minimum bends permitted are:
Minimum bend, light cable 60 mm (~2.5 in) radius
Minimum bend, heavy cable 82 mm (~3.75 in) radius
