Re: 4K Freesat Box
An official answer on the product page says
Question: Why does it have two tuners if it doesn't record?
Answer: Our 4K TV Boxes have two tuners because they are compatible with most UK satellite dishes, so if your box is connected to a dish with wideband LNB or standard LNB (using 2 cables) it will use one of the tuners to tune into the channel you’re viewing and the other to tune to our home transponder. This enables the box to receive programme information and any available software updates at the same time.
