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. The HFT1500 also features a precision frequency compensated lighted dual movement SWR meter. Included with the tuner is an unique Digital Bargraph Display that enables you to analyze peak SSB power measurements. Level and Delay controls are front panel adjustments.
