Hi

I have sky outputting an RF signal to channel 25 going to another room

We normally have this tuned in on an old SOny VHF/UHF TV and works fine

I am trying to tune to this channel 25 using a Freeview box tuned into channel 25 to pick up the sky channel and cant get it going

is it because the freeview box is only "digita"l as the RF is analog?

You don't say. How would you expect a DVB-T tuner to even know what analog PAL output from Sky decoder was.

The only way to get a UHF 'normal' signal to play nicely with a freeview or similar box is to use a DVB converter/injector. The last one I priced up that had four inputs was around 8000 pounds RRP.

So... unless you have lots of money you want to throw, it wont work.

Yeah.

Kind of like trying to put a CD in your cassette player.

yes, thought that was the case...

in some other forums, many people distribute a signal around the house through RF

so the new tvs that are now out that only have a free view DVT tuner wont be able to use this method

or do the current "new" tvs still have a legacy VHF/UHF + dvt tuner?

Most, if not all, of the new TVs still have analogue Tuners as well as digital.
Not much point in using the analogue tuner though as the signal is crap in comparison to the digital. I haven't even bothered to do a channel scan with mine.
You'd be better distrubuting your sky signal to your other room via composite, component, or HDMI. IMO the rf out from sky tuners (and VCRs etc.) has always looked awful.

Every new TV still has an analogue PAL tuner in it.

Using RF to distribute video around your house is the worst possible option when it comes to picture quality, you should really be looking at alternative options, particularly if you have a flat screen TV.

There have been a few smaller off brand TVs in AU that only had a digital tuner - things that are more the size of a PC monitor.

In saying that, the RF output of the skyboxes is so weak that distributing it directly has always failed for me. An amp is needed to get it up to the same levels as the off air stuff, then you can mix it into the RF. An amp on the antenna is needed to stop your sources broadcasting back out the UHF antenna. There are multiple input amps available if you are into sending RF around the place and you can get it looking as good as the off air analog if you tweek the levels just right, however thats not really saying much.
