aerial amp/splitter that will send DC power up the RF cable like a Sky box?

We've switched from Sky to Humax Freesat boxes recently.

I used RF1 to feed Freeview to the main TV & RF2 to the other 3 TVs in
the house. This also provided DC power to an amplifier/splitter
upstairs.

The Humax has only one RF out and doesn't provide DC.

Thus I currently have the old Sky+ box providing that function which is
a waste of electricity as well as space and is an unwelcome generator of
heat in this weather.

Is there an amplifier/splitter that could do what the Sky box does or
are there ways of decreasing the power use of the Sky box? (I guess
disconnecting the hard drive would be a start.

Thanks for any suggestions/ideas.

standalone power supply?

Easier than that even - Screwfix or Toolstation do them at very
reasonable prices.

Indeed, Toolsatan supply selected items from the Blake range last time I
checked.

So something like this?

Don't think so.

I thought you wanted something you could fit near the TV/STB which would
power an existing amp that's up in the loft or wherever?

That item would be a replacement amp which looks like it requires a
mains power supply?

It seems to be described as a satellite distribution amp, when I think
it's just UHF/FM.

If it's just an "inline" PSU you want

I need to split the RF into two by the main TV then power the
amp/splitter via the cable that runs upstairs. That device appears to
provide DC power up the coax. I assume that the Sky box provides some
amplification and that would do so as well.

The amp you are trying to power is, in fact, an amp, with gain. So you
most likely don't need any gain (amplification) at the satellite (or
other) receiver. So:
Buy a simple in-line PSU as others have recommended. Don't worry about
the voltage; 12V is fine for all amps, even when the label says 9V. Buy
a splitter. A screened one with f connectors is best. Connect the aerial
to the splitter input. Connect one splitter output to the adjacent
receiver. Connect the other to the 'out' socket on the PSU. Connect the
'in/amp' socket on the PSU to the cable that goes to the remote amp.
If it works, fine. If there's a bit of drop-out replace the splitter
with a mains powered one-in/two-out amp with a gain figure of 6 to 10dB.

This PSU will split two RF outputs, and shove DC up the input to feed
the amp, it won't amplify the two outputs though.

I *may* have one of those in a box somewhere.

Connect the aerial to the splitter input. Connect one splitter output
to the adjacent receiver. Connect the other to the 'out' socket on the

Such as the one I linked to at Toolstation..?.

Wouldn't it be simpler if I just bought that in the first place?
