Hi!
There are "squishy" cables that are designed to allow passage through window and door openings, however, they do fail...With the normal wear and tear of opening and closing the door/window, the cable becomes crushed and will eventually fail. Whether it is a day/week/year from now???? I've forbidden my techs from using them, as they are not on an "approved equipment" list...Especially for the incoming satellite signal. For the antenna (tv2) signal, they do better.
You can get these cable splices from a bunch of sources, but I just searched ebay for "cable satellite flat" and came up with a lot of them...Look there and see what they are...
Only pieces of advice....If you are going for the slim cables, buy a bunch to have on hand when they fail...Less frustrating if you can just reach over and put on a new one. #2 - talk with the (manager??) and ask for technical details about how holes may be drilled into the property. Point out that this is a system installation that will remain behind (cable and satellite dish) for the next tenant to use. If this is a multiple unit dwelling, have the building owner or manager call dish network and see about arranging an installation of the system "professionally" to their specifications and requirements...Getting them involved in the process might ease the blow of seeing satellite dishes on the property!
Good Luck!
