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.

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.

Note: Route the cable from the display up to the scanner, since this 
will require the smallest clearance hole.

The inter-unit cable, for connecting the scanner to the display unit, 
depends on your scanner package as follows:

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

Table 1-3: Inter Unit Cables required for each Scanner Type

2D (US)

10 m light (2 power cores)

2DE (European)

15 m light (2 power cores)

4D

15 m heavy (4 power cores)

5S, 7S (4 kW) and 9S, 11S (10 kW)
Note: 

All 10 kW systems require a

minimum of 24 V.

15 m heavy or radar arch kit 
(5 m + 10 m extension)
25 m heavy (24/32 V systems only)
