RFD-DQ106, 6 Elements Dual Band Quad for 10m and 6m Band.

RFD-DQ106 is a high-gain, low-noise, full-wave dual-band Quad antenna covering the 10 m and 6 m amateur radio bands. It features 3 full-size elements on each band, delivering excellent forward gain, high front-to-back ratio, and outstanding signal-to-noise performance. The antenna is constructed using high-strength fiberglass spreaders, a heavy-duty aluminium square boom, UV-resistant polypropylene (PP) clamps, and 2.5 sq. mm PVC-insulated pure copper radiators for long-term durability in harsh outdoor environments. Designed and optimized using advanced electromagnetic simulation with the correct dielectric constant of the insulated conductors, the RFD-DQ106 provides accurate real-world performance with no tuning. A single feed point efficiently excites both the 10 m and 6 m bands, allowing seamless dual-band operation without compromising gain, radiation pattern, impedance, or front-to-back ratio. The result is excellent performance on both bands with no noticeable pattern distortion or efficiency loss.
