HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual VECTRONICS HFT-1500 Digital Bargraph Antenna Tuner FEATURES The Vectronics HFT-1500 optimizes the performance of your antenna and transmitter or SWL receiver by providing adjustable impedance matching. The HFT-1500 also measures the Power and Standing Wave Ratio (SWR), which allows you to tune the indicted SWR to the lowest possible ratio for the selected transmit frequency.

HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual REAR PANEL CONNECTORS 1. RF INPUT Coaxial connector for input from SWL receiver or transmitter. 2. COAX 1 Coaxial connector for output to Antenna One. 3. COAX 2 Coaxial connector for output to Antenna Two. 4. BYPASS Coaxial connector for output to dummy load or third coax output. Bypasses tuner, but meter circuits and digital bargraph remain active if AC adapter is connected to the jack located on the rear panel. 5.

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.

HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual TUNING 1. Select the band and frequency of desired operation. 2. Set TRANSMITTER, ANTENNA, and INDUCTOR controls to the suggested settings before applying transmitter power. Actual settings may vary from antenna to antenna. BAND/ ANTENNA Actual INDUCTOR Sug. Actual TRANSMITTER FREQUENCY Sug. Sug. 160 M / 1.8 MHz 9.0 70 8.5 75 M / 3.75 MHz 7.0 280 7.0 40 M / 7.15 MHz 3.0 325 3.0 30 M / 10.125 MHz 2.5 350 2.

HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual controls for a minimum REFLECTED reading while maintaining a FORWARD reading of 50-100 watts using your transmitter power control. 9. Read the SWR on the red scale at the point where the two needles intersect. Repeat step 8 until the lowest SWR reading is obtained. The SWR should be 2:1 or lower. Note: This procedure takes patience the first time. The TRANSMITTER and ANTENNA controls vary the capacitors and provide fine adjustments.

HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual NOTES 1. An SWR or 1:1 is best, but an SWR as high as 2:1 may be acceptable. Check you transmitter manual for details. 2. If you cannot get an acceptable SWR, lengthen or shorten you antenna and/or feedlines and retune. 3. If you get low SWR readings at more than one setting, use the setting that: • • • Gives the highest FORWARD power reading. Gives the lowest REFLECTED power reading.

HFT-1500 Digital Antenna Tuner with Roller Inductor Owner's Manual METER CALIBRATION METER CALIBRATION PEOCEDURE • • • • • • • • • • Connect the HFT-1500 as depicted in Figure 9.1. Connect external 50Ω load to COAX 1 connector and the HF amplifier to the RF INPUT connector. Set the COAX 1 DIRECT position on the selector switch. Set the mid range the two capacitors on the RF sampler board and the four potentiometers on the switch board.

HFT-1500 Digital Antenna Tuner with Roller Inductor • • • Reverse the connections on RF INPUT and COAX 1. Select the 300 watt range on the RANGE button, apply 100 Watts of RF power at 7.0 MHz and adjust R2 for a forward reading on 100 Watts. Select the 3000 Watt range, apply 800 Watts of RF power at 7.0 MHz and adjust R1 for a reading of 800 Watts.
