Take a look inyour crawl space.
Any standing water?.....How about a light?..........How about the crap around your TVs? ......... The idiot will need access to the area around your TVs. Move the stuff around your house if you want the cable attached to the building............Find a way to tie up your dog and pick up the sh*t in the yard unless you want some tracked into your house. Call DTV about any promotional issues before the idiot arrives because he won't know anything about them,,,,,,,,,,,,,,,,AND...he may be dirty because he just left some other muddy crawl space.
The FREE basic installation is what it is and only idiots do them well or for very long. Expect to pay for additional services.
