The units are housed in aluminium tanks, silicone oil cooled to minimise losses and a major feature is broad band operation without the use of ferrite material in the transformer design.
- 50kW average, Type HF500
- 100kW average, Type HF1000
- 100 kW Average + 100% AM Mod
- Broad band 3-22 MHz
- Very low loss
- All-weather unprotected operation
These antennas require small size broad band matching networks and SMC offers the HF 1000 range providing 200 or 300 Ohm balanced outputs.
