Thank you for purchasing the AH-3 HF AUTOMATICANTENNA TUNER.The AH-3 matches your trans-INSTRUCTIONSceiver to an antenna more than 3 m/10 ft long (3.5 MHzand above)or more than 12 m/40 ft long (1.8 MHz andHF AUTOMATIC ANTENNA TUNERabove).AH-3Please read this manual thoroughly before AH-3 installa-tion and operation.DANGER/NEVER USE THIS TUNER WHEN IT IS UNGROUNDED.ALWAYS GROUND THE TUNER THROUGH THEGROUND TERMINAL BEFORE OPERATING.DONOT use the mounting plates for grounding.Ground terminal.NEVER TRANSMIT OR TUNE WITHOUT AN ANTENNA.Failure to use an antenna will damage the tuner.HIGH VOLTAGE!NEVER TOUCH THE ANTENNAMounting plateWHILE TRANSMITTING OR TUNING.Place the antennain a position where you are sure it will not be touched.FEATURES●NIDE TUNING RANGEEIGHT-FREQUENCY MEMORY FOR FAST TUNINGThe AH-3 provides reliable matching for frequencies fromThe LC combinations of 8 previously used frequencies3.5 MHz to 30 MHz when using at least a 3 m (10 ft)are automatically memorized in the AH-3.Once a fre-antenna such as the AH-2b ANTENNA ELEMENT (withquency is memorized,the AH-3 tunes on that frequencya 50 cm lead-in wire).in less than 1 sec.Note that the AH-3 does not memorizea frequency which is normally tuned within 2.5 sec.When operating above 1.8 MHz,use at least a 12 m (40 ft)Memories are retained only when the power is ON.antenna.●WEATHERPROOF DESIGNAUTOMATIC DIGITAL CONTROL TUNINGThe AH-3's tightly sealed plastic case allows convenientThe built-in 8-bit microcomputer chooses the lowestmounting virtually anywhere.The AH-3 can be mountedSWR condition from more than 260,000 different LCoutdoors under your antenna.(coil/capacitor)combinations.●0.3 W RADIATED POWERRadiated power during tuning is less than 0.3 W,minimiz-ing interference to other stations.UNPACKING②U-bolt plates,,2③Flat washers (M6 large).,,,,,,,,,,,··,,·······①④Flat washers (M6 small)),..,.·.,··,········。··4③Spring washers (M6),...,.··············⊙⑦Hex head bolts(M6x5o.,,,,,,···,,······g⊙⊙⊙⊙图Self-tapping screws(A06x30.,············⊙⊙⊙⊙■■⑨Strain relief inserts,·····@PL-259 connectors5.........·..。:·,,,··,····2④回回回回①Weatherproof cap,···················③@@四@@@00Control cable (5 m,connector assemblies)...........3 Coaxial cable (5 m).....国回回回回回回回回⑦
