Thank you for an excellent answer to a topic that has been bugging me for ages. I want to get rid of Direct because of expense and horrid customer service, but do not understand the new technology. When you say "antenna" I'm assuming you are not speaking of the thing my dad had to get on the roof to move, right? LOL Those were the days! Our internet service is not the greatest in this rural area, so I'm concerned we may not be able to use these devices. How can you test this?
