Portable Satellite Dish/using Kodi

Hi Everyone. First time poster in your excellent forums. Thanks for all your info. I would like to use a Kodi box very much,, my brother has it -looks fantastic, but can I in my mobile home?. We have a portable Satelite dish coming, with a Vast receiver- it will have the required cabling to connect my Foxtel box. Can I add a Kodi box to this arrangement? I also intend to get Telstra Mobile Broadband with probably 20 gigs/month data allowance. If I use the Kodi box to access Netflix will this cost a lot of gigabytes to watch a movie, or can I subscribe to Netflix and watch it via Satellite TV /Kodi box without the heavy gigabyte usage. Thanks for listening. We leave in our mobile home at the end of the month- hopefully able to watch some movies/documentaries. Regards, artsupial
