British catalogue retailer Argos launched its own shopping channel on Sky in June, as the firm searched for new routes to market amid a "significant decline" in sales.
Argos TV has now expanded to join Freesat at channel 819, broadcasting live product demonstrations and enabling viewers to make purchases direct from their sofa.
"With the Christmas shopping rush approaching, we're delighted to offer Freesat customers another great way to pick up deals or find the perfect gift," said Freesat's head of channels, Mark Briggs.
"Freesat is the fastest growing TV platform in the UK, and having recently hit the 2 million sales mark, we're constantly working to make sure we have a diverse set of channels to suit our growing audience. Argos is a key retail partner for us and we're delighted to have them on board."
Darren Frost, the head of Argos TV, said: "We are very excited about the launch of Argos TV shopping channel on Freesat as it gives us the opportunity to reach substantially more customers with another way to explore and shop the Argos range.
"Viewers will be able to watch the same shows at the same time that they are available elsewhere, 24 hours a day, seven days a week.
"As the UK's biggest retailer of Freesat devices we know that many of our customers are already using the service so it was a logical place for us to be. We are looking forward to our great programming being seen by a whole new audience."
Freesat has also confirmed that Chinese news service CCTV-NEWS will join its satellite TV platform this month, and will be available on channel 211.
