Tuning is required for each frequency. Be sure to retune
the antenna before transmitting when you change the fre-
quency— even slightly.
(eg. IC-7000)
Set the desired frequency in an amateur band. q
•The AH-4 will not operate on frequencies outside of ham
bands.
Hold down [TUNER/CALL] for 1 seconds. w
 •“ ” indicator appears while tuning.
Hold down [TUNER/CALL] for 1 second.
“ e ” indicator stays ON when tuning is complete.
 •Whentheantennacannotbetuned,“ ” indicator blinks,
and the AH-4 is bypassed and the antenna is directly connected
to the antenna connector on the transceiver.
To manually bypass the AH-4, push [TUNER/CALL]. r

INSTRUCTIONS
HF+50MHzAUTOMATICANTENNATUNER
AH-4
Thank you for purchasing the AH-4 HF + 50 MHz AU-
TOMATIC ANTENNA TUNER. The AH-4 matches your
transceiver to an antenna more than 7 m/23 ft long (3.5–
54MHz),ortheoptionalAH-2b(7–54MHz).
Please read these instructions thoroughly before installing
and operating the AH-4.
RNEVER operate this tuner without a solid ground. Always
connect the ground wire to the ground terminal. DO NOT use
the mounting plate as a ground terminal.
NEVERtransmitortunewithoutanantennaconnected.Fail-
ure to use an antenna will damage the tuner.
RHIGH VOLTAGE! NEVER touch the antenna while trans-
mitting or tuning. Place the antenna in a position where you
are sure it will not be touched.
DANGER!

45 FREQUENCY MEMORIES FOR FAST TUNING ❍
The LC combinations of 45 previously-used frequencies are auto-
maticallymemorized.Onceafrequencyismemorized,theAH-4
tunes on that frequency in less than 1 second. Note that the AH-4

WEATHERPROOF DESIGN ❍
The AH-4’s tightly sealed plastic case allows convenient mount-
ing virtually anywhere. The AH-4 can be mounted outdoors under
your antenna.
