HFT-1500 Digital Antenna Tuner with Roller Inductor
Owner's Manual

INSTALLATION
Carefully unpack your HFT-1500 from the packing carton and inspect it for signs of
damage. If any damage is apparent, notify the transportation carrier or dealer
immediately. We recommend keeping the packing carton for moving, storage, or
reshipping the tuner.
Select a location for the HFT-1500 that allows the connectors to be free of any possible
contact during operation.
WARNING: SOME BALANCED OR END-FED ANTENNAS WILL PRODUCE
HIGH RF VOLTAGES AT THE BANANA CONNECTORS. RF
BURNS MAY RESULT IF TOUCHED DURING TRANSMISSION.
INSTALLATION PROCEDURES
1. Connect a coax cable from your transmitter or receiver to the RF INPUT connector on
the rear panel. Keep the cable as short as possible. If you use a linear amplifier,
connect your transmitter to the linear amplifier output to the HFT-1500.
Do not use
more than 1000 watts average (single tone) through the tuner.
2. Connect coax cable(s) from your antenna to COAX 1 or COAX 2 connectors on the
rear panel. These connectors are either direct from the transmitter or through the
tuned circuit depending on the setting of the OUTPUT SELECTOR switch on the
front panel.
3. If you are using a balanced feed antenna, connect a balanced line to the BALANCED
OUTPUT connectors and jumper banana jack (8) with lower jack (7) as shown by
dotted line.
4. If using a single wire antenna, connect it to post (7) without installing jumper.
5. Connect a dummy load to the BYPASS (4) connector using a coax cable. This lets
you select the dummy load from the OUTPUT SELECTOR switch. Any antenna that
does not require the use of an antenna tuner may be connected to the BYPASS
connector, if desired.
BEFORE OPERATION
1. To avoid possible damage to the HFT-1500, set TRANSMITTER, ANTENNA,
INDUCTOR, and POWER RANGE switches as outlined in the next section before
applying transmitter power. (Tuning Section)
2. Begin tuning with your transmitter set at a low power setting
(50 to 100 W)
WARNING: DO NOT OPERATE THE HFT-1500 WITH THE COVER OFF!
