Description: 

Introducing RFD-SL/SQ2010 HF 5-Band Full-Wave Sky Loop / Single-Element Quad Antenna

Designed for 20–10 metres, the RFD-SL/SQ2010 offers two installation configurations from a single antenna:

Vertical Installation — Single-Element Quad:

When installed vertically, it operates as a 5-band, bidirectional full-wave quad. Radiation is strongest broadside to the loop, with front and rear lobes and deep nulls to the sides.

Horizontal Installation — Sky Loop:

When installed horizontally, the radiation pattern becomes predominantly omnidirectional in the horizontal plane, providing relatively uniform coverage in all compass directions. It also becomes horizontally polarized, making it an excellent choice when an Omni-directional antenna without a rotator is preferred.

Why RFD-SL/SQ2010?

  • 5-band operation: 20 / 17 / 15 / 12 / 10 m
  • Full-wave loop element for efficient radiation and naturally low-noise characteristics
  • Two installation options: Vertical or Horizontal
  • Bidirectional DX performance in vertical configuration
  • Omnidirectional coverage in horizontal configuration
  • No rotator required when used as a horizontal Sky Loop
  • Ideal for DXing, contesting and general HF operation
  • Designed with high-quality, durable materials
  • Built for high wind resistance and long-term outdoor service

The choice of installation depends on the operator's available space, desired radiation pattern, installation conditions and budget.

Whether installed vertically as a directional single-element quad or horizontally as an omnidirectional Sky Loop, the RFD-SL/SQ2010 delivers a highly practical full-wave-loop solution for serious HF operators.

One antenna. Two installation configurations. Multiple operating possibilities.
