ANTENNA CONSIDERATIONS
Always locate antennas such that they can never come in contact with outdoor power lines
in the event of a catastrophic support or power-pole structural failure. Ground your anten-
nas' support structure(s) adequately, so as to dissipate energy absorbed during a lightning
strike. Install appropriate lightning arrestors in the antenna coaxial cables (and rotator
cables, if rotary antennas are used).
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 FT-IOO transceiver or accessories, as
lightning can easily jump from the cable to the circuitry of your trans-
ceiver 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 instantly 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.
