Power Supply

The standard power supply for the VHF unit is 12V DC.
For 24V DC supply an external power supply with the type number N420 can be used.  The N420 is in
principle a 24V DC to 13.2V DC serial regulator.

For 110V AC, 127V AC, 220V AC or 237V AC operation, an external power supply with the type number
N163S must be used together with N420.

The fuse is a standard 10A mini car fuse. There is a spare fuse in the power cable connector.

2.3

Aerial

The transceiver without DSC requires one aerial. The transceiver with DSC is available in both a one- and a two-aerial
version.
All common 50

 aerials covering the used frequency range with a reasonable standing wave ratio, max. 1.5, can be

used.
Aerials are connected to the set by means of a 50

 coaxial cable with low loss, e.g. RG213U. For each cable, two

PL259 plugs are used, one mounted at each cable end.
