HC-1.5KAT FCC approved [Discontinued]
HF 1.5kW Auto Antenna Tuner
HC-1.5KAT is a high power HF auto antenna tuner designed to work with Tokyo Hy-Power HL-1.5KFX and HL-2.5KFX linear amplifiers.
When combined with these THP amplifiers, the band change is automatically made through the band data signal from the radio and the amplifier. It also works with other amplifiers as well, if band setting only is made in manual mode.
Tuning time is typically within one second and 2.5sec. max. in the worst case. It handles maximum power of 1.5kW pep/cw when the intrinsic antenna SWR is no more than 2.0.
Maximum impedance matching range is SWR of 4 to 1, and there are three antenna connectors.
Two of high quality 3kV rating 200pF air variable capacitors are employed to form a "T" match circuit being driven by high speed stepping motors.
Our own tuning algorithm together with an advanced 16bit micro-processor enables an extremely fast tuning.
