Analogue TV reception especially Channel 5 was always dodgy but all seemed OK with Freeview then that went pear-shaped on 3 TVs which were connected to the main TV aerial cable via a splitter. Bought this and all is now well so would say it does exactly what it says on the tin. NB It is a powered unit so make sure you have mains power socket available.
I needed to provide a feed to the TV and to two USB tuners in the Home Theatre PC. Freeview signals often don't survive passive splitters, so this did the job fine and I'm an area which is marginal for Freeview. Note that all connections on this unit are female sockets.
