Are satellite dishes allowed everywhere in the U.S.?

Well, you can thank your members in Congress for caving to the telecommunication lobby. As noted federal law permit one dish per household. There was research in the 1990 to allow your power company to carry signals to your house using the existing wire grid but local politicians always go for the cash rich new kid on the block.

There are some suburbs that place deed restrictions on all properties sold, and sometimes those can include banning satellite dishes. Those restrictions are valid and enforceable. For instance, if your neighbor puts one up, you can actually sue them to make them take it down. Similarly, some places restrict the right to put up flags, or restrict the type of home that can be built on the property. These are all valid restrictions.

They are allowed everyone as long as you can get a clear view to the right direction of the sky.People in suburbs are probably poor or middle income families.

Some municipalities do NOT permit dishes but sign a contract with one cable company.

Rentals don't permit anything to be attached to property.

Federal law states that all homes rented or owned may have a satellite dish one meter in diameter max on their roof.

So don't believe anyone who says you can't have a dish on your roof.

yes as long as there is a clear southern view
