I believe the REFLECTOR and the MAST do become the subscriber's, just as the inside wiring is all the subscriber's, as well. I think the logic is that the mast and reflector are physically ATTACHED (bolted) to the home/apartment, making it the subscriber's.
In my case, the fellow installed a brand new reflector and LNBF's and NEW mast. He did remove the reflector to be no longer used, but he left the mast as per his suggestion and my agreement. Sometimes leaving a mast (or even a useless reflector) is better than hoping one has properly sealed the holes were the bolts once were. This is a PROPER way to do it, and a way that will leak. Ours is on the roof visible only from the backyard, so I was pleased to have him leave the old mast as I knew for sure it did not leak (well, its on the eave, actually, but still a prevention of the wood rotting with the bolts still in place).
Dish seems not to think the LNBF's are not part of the "attached" equipment because they do ask for them to be returned or the subscriber is charged for the LNBF's. Dish does this, IMHO, to prevent piracy/theft of its service. However, no one has challenged this in court, and Dish could be WRONG on the LNBF requirement to be returned or the subscriber (former) charged for them as viewing LNBF's as "not attached" to the domicile. IMHO, I think it is morally wrong for Dish to expect anyone to climb the ladder to, often, a very dangerous point to just chop the cables and send in the LNBF (yes, I know Dish has waived this, but it should not be left to Dish's discretion). The LNBF's are chump change to Dish, and if ANY MVPD really wants to prevent theft of its signal, then it needs to invest in HIGH QUALITY encryption. After all, anyone (including pirates) can get Dish LNBF's for a pretty reasonable price and still be way ahead in the pirate game.
