Humax use to make the Aura 4k box for Freesat, but they aren’t anymore other than switching to Freeview and making the Aura Freeview box?
Aris now have the contract for making Freesat 4k boxes. Here’s the thing. there are no 4k channels on Freesat and only from streamed content, you can’t record.
There are other Humax boxes and boxes from other brands that allow you record but, are mainly HD and would require a LNB change. Given you Samsung isn’t 4k it might be something to consider, unless your thinking of upgrading your TV anytime in the near future. On the otherhand £250 isn’t alot compared to a Sky or Virgin subscription.
Something to think about 🙂
