The anti Sat Dish/Antenna issue is a non-starter argument for 99% Homeowners. Legally no HOA or Local ordinance could stop you UNLESS you are in an historic district (or condo/apartment where the outside is not yours). For a Private Residence if a HOA wanted to try to ban/fine you, they're just flat out going to lose and spend a lot of money losing. Line of Sight issues and personal decision is just about the only limiting factor. Rain Fade/Weather disruption for a properly tweaked dish is 100:1 better for DirecTV than any CableTV system even in the southeast thunderstorm zone.
Partially true, but legally not correct. You CAN be blocked from installing anything a neighborhood/community chooses if that is part of that areas code. For example, if you build a house it must look a certain way or be a certain style to match the community, be a minimum cost to build, be only a certain exterior theme/color, etc. It may also dictate what you may or may not put in your yard, on your roof, etc. Some are likely referred to "gated communities". You know full well before you buy a house there or build what the codes are, rules that are expected to be followed, etc. People pay a LOT of money to live in places like this so yes, there are places where those terms do not apply. Just wanted to clear that up because it's not a given.
