At my lovcation, I-9 at 58W is at an elevation of just over 23°. One mount-pole-dish will not allow anything that low. I therefor have to invert to get I-9 or anything further east of there.
Another possible use for a inverted ant is a temporary, vacation, take along, set-up.
Normally a tripod or "J'pole, a base of some sorts, and ballast to prevent the wind from upsetting it. If we invert, there is less wind resistance, as the dish is more to the horizontal.
Then we can dispense with the tripod or "J" pole and most, if not all, of the ballast.
Just a base with the dish mounted low, so as to pivot and pitch. Rain could be a detriment though, may have to drill a small drain hole.
