The PC-1000C4 Antenna tuning unit is designed to match 200-1500pF/2-30 Ohms antenna load in the 190-625 kHz frequency range, RF input power is 500 Watts peak.
The coupler has an auto-tune feature which automatically maintains system match and tuning during changing environmental conditions and antenna characteristics. A variable coil ensures resonance is maintained while resisttive matching network ensures the transmitter always sees a 50 Ohm load thus minimizing VSWR.
The unit is housed in an IP66-Certified aluminum enclosure with latches for all weather operation. Operating power is supplied by SAC transmitter or optional 100-264VAC internal power supply.
