4.1. Grounding
The amplifier has to be grounded properly! Connect the screw on the rear panel of
the amplifier to your local grounding system with a copper cable; use a cross-section
of 4 mm
2
at least.
Connect your transceiver to the same grounding system of your shack carefully! Use minimum
length cables and make certain that the connections are both physically and electrically sound. With
poor grounding, you may risk damaging your equipment, having problems with TVI/BCI or your
transmitted signal may be distorted.
4.2. Coaxial Cable
The output of the transceiver is to be connected to the input of the amplifier via RG58 or similar
cable. For the connection between the power amplifier and the antenna, RG213 or similar coaxial
cable suited for high power is recommended. At the INPUT and OUTPUT SO-239 sockets with
Teflon insulation are used.
