Well, for that 4.5m I have two choices - Obtaion official permission to use it (but owner is unknown), or pay $100 to guardians, to let me readjust it hiddennly at night.
Of course, larger is the dish, sharper is the focus, and nearby noises are cut off much more effectively, but it can't help with atmospheric interference, which becomes very prominent on such low elevated sats.
Regarding the 12 meter dish, I was able only to saw it's back side by glimpse. According to it's design, I can guess it's channel master product. This dish is located in private property (Former MMDS tv company property, now abandoned), and surrounded by trees, so it's almost impossible to come closer and check details.
Thanks for country praising, it's quite beatifull, especially for fresh, foreigner eye

But there's one big disadvantage - here's no place, where you eyes can rest, by looking into horizon. Here, mountains are from everywhere
