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.
