Antenna Precautions
Always locate antennas such that they can never come in contact with outdoor power lines
in the event of a catastrophic antenna support or power line support structure failure.
Ground the support structure adequately, so as to dissipate energy absorbed during a light-
ning strike. Install appropriate lightning arrestors in the antenna lead-in and rotator cable
(if used) according to the arrestor’s instructions.
In the event of an approaching electrical storm, disconnect all antenna lead-in, rotator
cables, and power cables completely from your station if the storm is not immediately in
your area. Do not allow disconnected cables to touch the case of your
VX-1400
trans-
ceiver or accessories, as lightning can easily jump from the cable to the circuitry of your
transceiver via the case, causing irreparable damage. If a lightning storm is in progress in
your immediate area, do not attempt to disconnect the cables, as you could be killed in-
stantly if lightning should strike your antenna structure or a nearby power line.
If a vertical antenna is utilized, be certain that humans and/or pets and farm animals are
kept away both from the radiating element (to prevent electrical shock and RF exposure
danger) and the ground system, in the event of an electrical storm. The buried radials of a
ground-mounted vertical antenna can carry lethal voltages outward from the center of the
antenna in the event of a direct lightning strike.
Heat and Ventilation
To ensure long life of the components, be certain to provide adequate ventilation around
the cabinet of the
VX-1400
. The cooling system of the transceiver must be free to draw
cool air in from the bottom of the transceiver and expel warm air from the rear of the
transceiver.
Do not install the transceiver on top of another heat-generating device (such as a linear
amplifier), and do not place equipment, books, or papers on top of the transceiver. Place
the transceiver on a hard, flat, stable surface. Avoid heating vents and window locations
that could expose the transceiver to excessive direct sunlight, especially in hot climates.
