Couple of things Swampman.
The Zenith dish I believe is a Winegard Pinnacle. It may have Zenith's name on it, but it certainly looks like a Pinnacle. Look at how deep it is, and look how close to the edge of the dish the feed-horn is. The outside rim is identical, and the ribs on the back are the same.
It is a Pinnacle in Zenith disguise. A very good perforated dish, but difficult to peak with a balance of C and Ku if you use a Co-Rotor II on it. Perforated aluminum. Very tough, and small holes.
Second thing about the dishes on poles. Think young men who are very strong with a couple of ladders against the pole, or lift truck. The dish by itself isn't that heavy. The mount weighs around 100 Lbs. Young strong men can do a lot.
Too bad those days are behind me.
