Meet the RFD-4MQ2010, Ultra High Gain and Ultra Low Noise 4-Element, 5-Band HF Quad

Engineered for serious DXers and competitive contesters, the RFD-4MQ2010 delivers outstanding performance across the five major HF amateur radio bands from 20m through 10m. Designed for demanding operating environments, it combines a robust mechanical structure with an innovative multiband feeding system.

Advanced Engineering. One Reliable Feed.

While many conventional multiband quad antennas depend on band-switching arrangements, separate feed systems, or quarter-wave stub matching, the RFD-4MQ2010 uses our Parallel Transmission Line Single-Feed System.

This architecture provides a common single-coax feed across all five bands, supporting consistent, dependable multiband operation without switching between separate feed systems.

Heavy-Duty Construction for Long-Term Performance

Radiating Elements

  • 2.5 mm² pure copper wire with 0.8 mm PETG insulation for enhanced outdoor protection.
  • Approximately 9 kg of copper wire used across all five bands.

Telescopic Fibreglass Spreaders

  • Telescopic construction ranging from 32 mm to 22 mm outside diameter.
  • 2 mm wall thickness for a strong, practical structural design.

Heavy-Duty Aluminium Boom

  • Three aluminium square-tube sizes: 60 × 60 × 3 mm, 50 × 50 × 3 mm, and 40 × 40 × 2 mm.
  • Approximately 30 kg of aluminium boom structure alone, built to meet demanding mechanical requirements.

Professional-Grade Hardware

  • SS-304 stainless-steel boom truss support wire.
  • SS-304 stainless-steel fasteners and fittings throughout.

Built for Serious DXing and Contesting

The RFD-4MQ2010 is designed for operators who want to capitalize on every opening, overcome challenging propagation conditions, and compete confidently in crowded pile-ups.

Whether you are pursuing rare DX stations, taking part in major contests, or maximizing the potential of low-power operation, this antenna is engineered to provide a capable and dependable station presence.

When propagation is challenging and every contact matters, your antenna system can make the difference.
