GTV 50-6m Yagi   with bent Driven Element

This is medium length 6m band Yagi with high F/B and good G/T. The bent DE (K6STI style) transforms from low impedance to 50 ohms
at feed point for direct feed.
Date of issuing this design : 04th of Apr. 2024



GTV 50-6m at BG9MM





GTV 50-6m built by BG5TOX, Xu Da et al.
