Winegard YA-1713 with Detailed wire model for the Boom and Crossover feedline (instead of TL Card) analyzed using 4nec2. Includes Boom Correction.
It does not appear that 4nec2 has sufficient numerical accuracy to model the tiny wire segments in Boom, which is why Yagi's are normally modeled WITHOUT the Boom, using a Boom Correction instead.
HENCE THESE RESULTS CAN NOT BE BELIEVED!!!
