5. EXTERNAL GROUND CONNECTION
WARNING! Before connecting an external ground as described below, check
with a qualified electrician that your national wiring codes permit such a
connection.
To reduce TVI, BCI and other RF problems it is sometimes helpful to connect the
amplifier to a good RF ground.
The inductance of such a connection has to be low, so the connection to ground should
be as short and direct as possible. Large-section copper conductors should be used for
this purpose. Terminating the earth connection with a small metal plate is suggested.
The best solution is to have a ground stake, driven into the ground, and used only for
the radio station.
Often good results can be achieved using correct earthing clamps, connected to the
main water supply pipe (attention, most water pipes are now in plastic).
DO NOT use central heating pipework.
AVOID the electric circuit ground of the building (to be used for 50/60 Hz safety only).
WARNING! DO NOT
connect to gas pipes because there is danger of explosion !!
