I have an off grid second property. There right now.
I use a yagi antenna for cell sevice, which I then use for Internet via my iPhone hotspot. No additional cost.
I can get 3 TV networks OTA but just barely and not reliably. So I use satellite for TV.
Because I use Dish Networks at my first home I could probably just take a Dish receiver from there and get free satellite with a Tailgater or an installed dish. But for convenience I set up a separate Dish account and a 200 channel plan. I am on vacation mode 6 months of the year for $5/month. Costs @$500 annually.
Works very well for me.
We have a very rural vacation home and that is pretty much what we did. (we rarely use it anymore so I am going off memory). If I recall correctly, you have to call and let them know you will be there and they turn it on--
I like your set up. Hm. I need to speak to dish about this. They have always been very good to us.
