The Winegard HD6065P is a log-Yagi array with ten elements on a 125″ boom. Four of the elements are driven. A shorted transmission line terminates at a passive reflector.
Winegard discontinued the HD6065P and replaced it with the HD6055P, an eight-element design on an 82″ boom.
I modeled the antenna with the AO 9.67 Antenna Optimizer program. This image shows the antenna geometry.
This shows segmentation detail for the phasing lines and feedpoint. Blue dots mark analysis segments. The red dot is the feedpoint. The lower phasing lines connect to rivets at the underside of the driven-element insulators, while the upper lines connect directly to the elements on top. The rivets electrically lengthen each lower line section by 2″. This causes some pattern asymmetry visible in the plots below. Narrowband dips near 89 and 103 MHz are visible here.
The antenna has a plastic feedpoint box that snaps onto parallel feeders. The box contains an F-connector and a printed-circuit matching network consisting of thick and thin PCB traces, shunt capacitor, and dual-core ferrite balun. I removed the feedpoint box and measured the 75Ω return loss as > 40 dB at 98 MHz (> 25 dB over 88–108 MHz) with 130Ω and 9.3 pF across the feeder terminals. I set the SWR reference impedance to the series equivalent, 83.6-j62.3Ω.
The phasing lines surround a 1″-square boom, but the upper and lower lines are not equidistant from it. This may couple unwanted signals. I did not model this effect.
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.
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.
