I believe it is CHEAPER not to have to go and unmount and disassemble an old reflector and LNBF, switch, etc., and then go to the new place and reassemble and re-mount. My belief has always been that the reflector is incredibly cheap for Dish. Further, even the relatively expensive for RETAIL LNBF's and switches are also FAR MORE Cheaper for Dish than we might think. In the past, with upgrades, the installer would take the equipment with them in their vans. I asked what they did with them and they said they just threw them out with the trash. They didn't want to leave them as a mess for the customer. I'm talking a complete upgrade of reflector, LNBF's and "expensive" switches. No, they said they do not re-use the switches--that is Dish Corp. installers did not re-use them; independent retailers probably do.
Now, get this: with my last upgrade to Hopper just last November, it was another COMPLETE hardware upgrade with NEW reflector and NEW LNBF's and replacing my TWO DPP44 switches. He took all that equipment and put them in MY garbage bin! I can't remember if he put the reflector, as well, but I have every confidence they never re-use those. So, this last upgrade further confirmed my belief that they just throw them out. However, an independent retailer may re-use some of the switches to save themselves some money.
I believe Dish throws out used reflectors, LNBF's, and switches partly because it is cheap enough for them to do so, certainly avoiding the additional cost of taking down reflectors, etc, and switches for a Dish Mover: cheaper just to install new stuff at the new home.
The other reason is, IMHO, is that Dish doesn't want to gamble with the customer experience: in other words, if Dish were to re-use the old LNBF's, and switches (and I mean if they no longer need that switch for that install such as in my case of replacing and throwing out TWO DPP44's with Hopper Nodes, etc.), that old equipment could malfunction or die a lot sooner than if they just used all NEW equipment for all Dish Movers and installs (again, leaving in place equipment that can still be used, but if they take it out, they do NOT use it again), and this provides for a greater chance of POSITIVE customer experience AND LOWER COST to Dish because they don't have to send a tech out AGAIN, to replace old re-used parts and only get $15 of the cost covered or even the $99 tech visit fee is NOT cover additional labor and new parts cost to replace re-used equipment. Who knows how much longer the re-used equipment will last? After years of being weather-beaten under the sun, etc., they could last years, or months, or days. To a big company like Dish, it is too expensive and too big a risk, so they just replace everything with NEW equipment, if necessary.
Now, the STB is a different matter, and can be re-used to high efficiency, and the STB's are more expensive than the really cheap stuff that make up the rest of the system. Keep in mind, Dish is a really big buyer, so Dish's cost on what are expensive retail items are gonna be so low that it does make economic sense, especially when factoring in the "hidden" costs to re-using all equipment except for the STB's.
BTW, I went back and retrieved both of my DPP44's that the installer threw out into my garbage bin. Everything else was left in the garbage as I did not see any value in them. Although I should have taken the reflector because I've had situations where a few people just needed a reflector (the mount is cheap to buy on Amazon at retail) to get started on Dish without a contract or other high cost (the LNBF's can also be had retail) because it is the reflector and assembly that is truly over priced at retail sites. In fact, it is the retail price of the reflector and assembly that blows out any savings with a DIY for those who do not want to commit to 2 years. Oh, well. Live and learn.
Just my two cents.
