without a ground plate, unless the vessel has a steel hull. Before
installing the transceiver in a boat, consult your dealer for information electrolysis
between fittings in the hull and water.
3-Way Combinations Antennas are available which allow operation of all three bands
(AM-FM & CB), using a single antenna. However, use of this type of antenna usually
results in less than normal transmit and receive range when compared to a
standard-type “Single Band" antenna designed for CB only.
Ignition Noise Interference
Use of a mobile receiver at low signal levels is normally limited by the presence of
electrical noise. The primary source of noise in automobile installations is from the
alternator and ignition system in the vehicle. Under most operating conditions, when
signal level is adequate, the background noise does not present a serious problem.
Also, when extremely low level signals are being received, the transceiver may be
operated with vehicle engine turned off. The unit requires very little current an
therefore will not significantly discharge the vehicle battery.
Even though the supernova radio has an automatic noise limiter, in some installations,
ignition interference and other forms of automobile generated noise may be high
enough to make good communications difficult. The electrical noise may come from
several sources. Many possibilities exist and variations between vehicles require
different solutions to reduce the noise. Consult your supernova dealer or a 2-way
radio technician for help in locating and correcting the source of severe noise.
Base Station Operation (Operation from 120VAC, House Current) To operate your
transceiver from your home or office, using the regular house current as the power
source, you will require a 12VDC power pack that has been specially designed for
the purpose. It is available as optional equipment from your supernova dealer. It
consists of a 120-volt, 60 Hz AC to 12-volt DC power converter with a 3A rating.
Simply connect the red (+) and black (-) leads of the transceiver to the corresponding
terminals of the power packs.
DO NOT ATTEMPT TO OPERATE THIS TRANSCEIVER BY CONNECTING
DIRECTLY TO 120 VAC. SERIOUS DAMAGE WILL RESULT.
Temporary Mobile Operations
To operate your supernova transceiver from a car on a temporary basis, you may want
to purchase an optional cigar lighter adapter from your supernova dealer. This adapter
and a magnetic mount antenna allow you to quickly "install" your transceiver for
temporary use.
