9390 transceiver and control head grounding
Grounding the 9390 transceiver or control head is
unnecessary for most installations. If RF interference causes
transmit distortion, you may need to ground either or both
units.
The transceiver chassis is connected to battery negative and
will be DC isolated from ground when installed with the
cradle (see Installing the transceiver on page 2-5).
If the transceiver needs to be grounded, use a code 733B
Aerial DC Isolator to isolate the transceiver when connecting
to the antenna tuner and the RF earth point.
To earth the control head, earth the mounting bracket by
ensuring that the screws holding the mounting bracket are not
insulated. It may be necessary to remove paint from around
the screws to ensure a good contact.
