1. Features
The AT1KD optimizes the performance of your antenna and transmitter or SWL
receiver by providing adjustable impedance matching using a T-type circuit
configuration with a dual-stator differential variable capacitor. The AT1KD also
measures the power and Voltage Standing Wave Ratio (VSWR or SWR) which
allows you to tune the SWR to the lowest ratio possible for the selected
transmission frequency. The AT1KD also features a precision roller inductor
with a steatite ceramic core. The innovative differential capacitor design simplifies
operation by reducing the number of knobs and eliminates false peaks while
tuning. It also results in a more compact case that takes up less room on the
operation desk.
