Fuse
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 50Ω 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 50Ω coaxial cable with low loss, e.g. RG213U. For each cable, two
PL259 plugs are used, one mounted at each cable end.
