That type of amplifier ("masthead") needs power fed to it via one of its outputs. You need something like the white box here between one of your TVs and the wall.A six way splitter like that will weaken the signal too much unless you have a masthead booster before it.
If you have a mains socket handy under the stairs it's probably easier to swap the amplifier to a conventional one.

Interesting, this is my actual one and it does seem to suggest there should be power (I don't know which room that goes to). Are power supplies for those pretty generic do you know? The internet isn't telling me much
Aerial is only in the loft and there is power up there so I could try a masthead amplifier up there I guess.
I do have a mains socket under the stairs too for a conventional powered splitter.

When I moved into my house it had been all wired up for a tv aerial with aerial points in each room and one of these under the stairs linking it all to the aerial wiring in the loft:
There wasn't an aerial installed but I traced the wiring up to the loft using one of these and connected an aerial.
It doesn't work. The aerial does work (I put a wire down the chimney breast and connected it to my tv and it works fine) so it must be somewhere in the wiring which has a fair few joins (but still shows continuity from the downstairs aerial point to the wiring in the loft).
Any suggestions for tracking down where the issue arises that doesn't involve me wiring up a freeview box and screen at each join to see where it stops working? Cheers
