AN IMPORTANT WORD ABOUT POWER LEVELS
The AT-897Plus is rated at 125 watts maximum power input. Many ham transmitters and
transceivers, and virtually all amplifiers, output well over 125 watts. Power levels that
significantly exceed specifications will definitely damage or destroy your AT-897Plus. If your
tuner fails during overload, it could also damage your transmitter or transceiver. Be sure to
observe the specified power limitations.
AN IMPORTANT WORD ABOUT TUNING ON THE SIX METER BAND
The AT-897Plus is designed to tune loads on 6m that start out at 3.0:1 SWR or lower.
Attempting to tune a greater than 3.0:1 load on six meters at full power can damage your AT-897
tuner. Power levels in excess of 50 watts should be used on 6 meters only if the SWR of the load
was lower than 3.0:1 prior to tuning. If you are unable to check, or are unsure of the SWR
of the load prior to tuning, be sure to reduce power to 50 watts or less when operating on
six meters.
IMPORTANT SAFETY WARNING
Never install antennas or transmission lines over or near power lines. You can be
seriously injured or killed if any part of the antenna, support or transmission line touches
a power line. Always follow this antenna safety rule: the distance to the nearest power
line should be at least twice the length of the longest antenna, transmission line or
support dimension.
