The Winegard HD-6000 is a dual-drive Yagi with four elements on a 31″ boom. Winegard used to call it the ProStar PR-6000.
I modeled the antenna with the AO 9.67 Antenna Optimizer program.
This shows phasing line detail. The red dot is the feedpoint and blue dots mark analysis segments. One phasing line connects directly to the elements, while the other passes through inch-long rivets. The unequal line lengths cause some pattern asymmetry visible in the plots below.
Bryce Foster used this HD-6000 indoors at Murfreesboro, Tennessee.
The reflector of one HD-6000 measured 64.5″ long, another was 65″, and Winegard specs the maximum width of the antenna as 65.5″. The image to the left shows tubing interference at the center of the 64.5″ reflector. I used 65.5″ in the model.
The driven elements mount to plastic center insulators with metallic locking flanges. The slits on each side inhibit current over most of the flange length so I did not model them.
The model does not include the 300Ω balun that comes with the antenna. Subtract 0.75 dB from the forward gain figures to account for its loss.
Calculated performance is for 28 analysis segments per conductor halfwave. Forward gain includes mismatch and conductor losses. F/R is the ratio of forward power to that of the worst backlobe in the rear half-plane.
