HF200 Series – 20kW HF Wide Band Antenna Matching Transformer

The HF200 Series is a 20 kW average power transformer suitable for communications or broadcast systems.

The units are housed in a finned cast aluminum tank which provides excellent natural convection cooling. Each casting is subjected to a double vacuum resin impregnation process which ensures complete sealing for the internal low loss silicone cooling oil.

High purity alumina ceramic insulators with arcing horns are fitted as standard and an internal static drain to earth provides additional protection against lightning-induced high voltages.

  • Wideband 1.5 to 32 MHz
  • 20 kW average + 100% AM modulation
  • Suitable for communication or broadcast application
  • Very high efficiency
  • All-weather unprotected operation

A wide selection of unbalance and balance impedance ratios are available to complement most antenna configurations and inquiries for non-standard arrangements are welcome. The HF200 is a high-quality unit suitable for unprotected operation in any environment.
