HF30 Series – 3kW HF Wide Band Antenna Matching

HF30 Series – 3 kW HF Wide Band Antenna Matching

The HF30 Series of antenna matching transformers are solid encapsulated heavy-duty units suitable for the most arduous environmental conditions and designed for installation in any orientation.

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. An internal static drain to earth provides additional protection against lightning induced EMFs.

  • Wide band 1.5 to 32 MHz
  • 3 kW average, 12 kW PEP
  • All weather solid encapsulated
  • Heavy duty cast aluminum case

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.

The HF30 is a unit of the highest quality and reliability.
