HF10 Series – 1kW HF Wide Band Antenna Matching

HF10 Series – 1 kW HF Wide Band Antenna Matching

The HF10 Series of antenna matching transformers are fully encapsulated heavy duty units designed for the most arduous environmental conditions.

The transformers are housed in a cast aluminum case, vacuum impregnated with epoxy resin and finished in epoxy paint for added protection. High purity alumina ceramic insulators with arcing horns are fitted as standard and an integral static drain to earth provides additional protection against lightning induced EMFs.

  • Wide band 1.5 to 32 MHz
  • 1 kW average, 4 kW PEP
  • All weather solid encapsulated
  • Fixed station or transportable antenna arrays

For added EMP proof operation no capacitors are used in the transformer circuit. A wide selection of unbalanced and balanced impedance ratios are available to complement most antenna configurations and enquiries for non-standard arrangements are welcome. No compromise has been made to provide a unit of the highest standard of reliability.
