FT-847 OPERATING MANUAL
Installation
GROUNDING
Mobile Station Grounding
Although satisfactory grounding in most installations
will be achieved via the DC cable’s negative lead and
the antenna system’s coaxial cable shield, it is often
recommended that you provide a direct ground con-
nection to the vehicle chassis at the mounting loca-
tion of the transceiver. Due to unexpected resonances
which may naturally occur in any location, improper
communication system performance may result from
insufficient grounding. These symptoms may include:
l RF feedback (resulting in distortion of your
transmitted signal);
l Unintended frequency change;
l Blinking or blanking of the frequency display;
l Noise pickup; and/or
l Loss of memory.
Note that these conditions may occur in any commu-
nications installation. The FT-847 includes extensive
filtering designed to minimize the chance of such prob-
lems; however, random currents set up by insufficient
RF grounding can nullify such filtering. Bonding the
rear panel Ground lug of the FT-847 transceiver to the
vehicle or vessel’s ground system should clear up any
such difficulties.
Yaesu does not recommend the use of “on glass” mo-
bile antennas unless the shield of the coaxial cable is
securely grounded near the feedpoint of the antenna.
Such antennas frequently are responsible for the
ground-related difficulties described above.
