To be fair, many homeowners who don't intend to have satellite tv find the dishes unsightly. One of the first things I did when we bought our house was take down the two easily reached dishes that we weren't going to use ever; the one that was way up there got to stay, but I did remove the cable that was running outside all over the place.

From what I understand, it's pretty common for the next satellite installer to want to install a completely new dish and LNB when service is requested, unless the dish is very recent.
