HF50 Series – 5kW HF Wide Band Antenna Matching Transformer
The HF50 5kW series are solid encapsulated and suitable for installation in any orientation.
The transformers are housed in a heavy duty cast aluminium case, vacuum impregnated with epoxy resin and fully hermetically sealed for any military or commercial environment.
- Wide band 1.5 to 32 MHz
- 5 kW average, 20kW Peak
- All weather solid encapsulated
- Heavy duty cast aluminium case
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 EMFs.
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 HF50 is a unit of the highest quality and reliability.
