WS734115 34 element yagi is a unique design, a true Advanced OWA, and will stand up to examination in any software package... Seen here in 4nec2 by Arie Voors, YAGIMAX 3.51 by the late Lew Gordon K4VX, and K6STI's AOP (AO Professional)!
Because of the large diameter driven element segmentation cannot exceed 22 segments per λ/2 and has been set at 20 (Auto segmentation) for tuning purposes!
Reactance has been contained within very tight limits (+j7.0Ω to -j3.0Ω) so enabling a high degree of stability along with maximum performance. This has been achieved by the use of a two-tier tightly coupled director cell (D2/3 and D4/5). The result, average Q-factor shows a shallow gradient like that seen in a highly stable DL6WU long yagi antenna...
