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 engineered to thrive in the most challenging environmental conditions.
These transformers are securely housed in a cast aluminium case, vacuum impregnated with epoxy resin, and finished with epoxy paint, providing an extra layer of protection.
Key Features:
  • Broad band coverage from 1.5 to 32 MHz, ensuring compatibility across a wide range of frequencies.
  • Impressive power handling capabilities – 1 kW average power and 4 kW peak envelope power (PEP), meeting demanding requirements.
  • Solid encapsulation design ensures all-weather resilience, ensuring reliability in any condition.
  • Suitable for both fixed station and transportable antenna arrays, offering versatile deployment options.
  • High purity alumina ceramic insulators with arcing horns come standard, delivering enhanced performance.
  • Equipped with an integral static drain to earth, providing additional protection against lightning-induced electromagnetic fields (EMFs).
  • For enhanced EMP-proof operation, no capacitors are used in the transformer circuit, ensuring reliable performance in critical scenarios.
The HF10 Series stands as a testament to uncompromising reliability, delivering exceptional performance in the most demanding applications. Elevate your antenna system with this pinnacle of transformer technology, ready to conquer the challenges of any environment with unwavering confidence.
