RadioHub 7-Element Tri-Band HF Yagi Antenna (20m/15m/10m)

The RadioHub 7-Element Tri-Band HF Yagi is a high-performance directional antenna engineered for serious DX work on the 20-metre, 15-metre and 10-metre amateur radio bands. With 7 active elements spread across a 4.10 m boom, it delivers strong forward gain and front-to-back rejection for long-distance contacts.

 

Element configuration: 3 elements active on 10 m, 2 elements active on 15 m, and 2 elements active on 20 m — each band gets its own optimised elements on a single shared boom for true tri-band directional performance.
