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, have problems with TVI/BCI or possible distortion of
your transmitted signal.
4.2.
Coaxial Cable
The output of the transceiver is to be connected to the input of the amplifier via RG58 or similar 50 Ohm
cable. For the connection between the power amplifier and the antenna, RG213 or similar coaxial cable
suited for high power is recommended. SO-239 sockets with Teflon insulation are used for the HF INPUT
and OUTPUT connectors.
