Vacation home?
Could we use this instead of having a separate cable subscription at a cabin? Like using our home cable subscription at the cabin? Would we need a roku, apple tv or other for each tv at the cabin?
Yes and yes, but you would have to have INTERNET with WiFi or hardwired to the devices you mentioned at your cabin. You could use a smartphone with a huge data plan If you don't have internet there. (that's expensive unless you have unlimited data). One slingbox at home = one channel at your cabin. It's not like you can watch one program on your TV and the kids watch theirs on another. That in mind do you need a second roku if you all have to watch the same channel? If you don't want to hang out together or want to watch at different locations (bedroom?) any of the devices you mentioned would work. If you want to get different channels on the other tv you would have to have a second slingbox at home hooked up to a second cable box at home and a second slingbox account. Don't forget to leave your cable box(es) on when you leave home your slingbox mirrors what's on in that box. You don't have to leave your tv's on at home just the cable boxes. The slingbox 350 requires you connect via hardwired or have a wireless converter. You may want to consider an M1 slingbox (or two) if you need different channels as that one is wireless assuming you don't have access to cat 5 cable at both source cable boxes at home. Disclaimer I don't have two slingboxes at home just one, but know how they work so the part about two slingboxes isn't personally proven. Save your receipt in case you want to return one If that part doesn't work.
