HF30 Series – 3kW HF Wide Band Antenna Matching

HF30 Series – 3 kW HF Wide Band Antenna Matching

The HF30 Series of antenna matching transformers, the epitome of solid encapsulated heavy-duty units engineered to thrive in the most challenging environmental conditions. Versatile in installation, these transformers are suitable for any orientation.

Key Features:

  • Broad band coverage from 1.5 to 32 MHz, ensuring compatibility across a wide range of frequencies.
  • Impressive power handling capabilities – 3 kW average power and 12 kW peak envelope power (PEP), meeting demanding requirements.
  • Solid encapsulation design guarantees all-weather resilience, ensuring reliability in any condition.
  • Constructed with a heavy-duty cast aluminium case, vacuum impregnated with epoxy resin, and finished in epoxy paint, providing added protection.
  • High purity alumina ceramic insulators with arcing horns come standard, delivering enhanced performance.
  • Equipped with an internal 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.

Experience unmatched flexibility with a wide selection of unbalanced and balanced impedance ratios, catering to most antenna configurations. We welcome inquiries for non-standard arrangements, ensuring a tailored solution for unique needs.

The HF30 Series sets the standard for quality and reliability, delivering exceptional performance in the most demanding applications. Elevate your communication setup with this pinnacle of transformer technology.
