I have an unused pole mount for a 105 Superdish antenna (2" OD IIRC) that I'd like to adapt to fit a standard Dish 500 antenna (1.25" OD maybe): other than thru-bolting & some serious bushing between the outside of the smaller mast & the inside of the larger Superdish pole, is there a way to do this adaptation that's easy & stout?? Thanks for any help....John
