Ok, so I got it working. Combination of the electrician and hints from here. Thanks.

Result is arial to splitter which has 4 feed inputs. Unit 1 then goes to unit 2 and then up to splitter which combines it for all TVs.

Working perfectly.

I'm using one of the cheapish Aliexpress hdmi-DVB-T modulators - search there for "HDMI DVB-T Modulator Convert HDMI Extender signal to digital DVB-T HDMI TO DVB-T"

 

I only need one as only inject Sky decoder into the house's TV cable distribution. These things don't seem to do HDCP so you need to strip that out with a cheap HDMI splitter or similar. That's a PITA as you end up with double the power supplies and a mess of wires, but it seems to work perfectly and has been running for months without issue.

 

You select the UHF output channel via dip switches, so I would assume that if you had more than one of these, you could inject them all with different channels using a diplexer.

The cheap aliex ones dont do LCNs when I last had a play with one. This meant that some TVs would not show the channels, others put them on stupid numbers that you have no ability to move them around to a more sensible number without turning LCN on the TV off which made all sorts of other junk channels get in the list.

Have been using a Satlink WS 6990 Hdmi Modulator for the past few years here. Has been great. Accepts either composite and or Hdmi video input. Allows full configuration LCN , channel Name, dbuV output level etc.
Cost me about $190 Nz and hadn't missed a beat.

The best thing about configurable LCN (Logical channel number) is that you can just choose an un used channel number in the freeview Mux and that's where your modulated channel will appear - with it's own channel name.

Found mine on Aliexpress. Have installed about a dozen up and down the country.

Hey Rentakill, I have a WS 6990 too, works great, just one bugbear, each time change between a freeview channel and the WS6990’s channel, I get the scrolling message at the top of the screen “The broadcasters signal information has changed, a DTV rescan will start to update this info [yes /no buttons]”. I just ignore but is a bit of pain. This only happens on my Samsung TV, Other TVs aren’t bothered.
Is this something you have come across or know how to resolve?(or anyone else).

I do have a second Digital modulator (unbranded type with dip switches to set frequency and no LCN etc) which doesnt display the issue above. it was slightly cheaper than the satlink, picture just as good, (1080 output...) so tend to use this one for Sky.


Also one thing to note with Digital modulators, due to processing required, there is a second or two delay compared to original HDMI output, ok for normal channel changes, but if fastforwarding / resuming playback, easy to wizz past start of programme after ad break.

Yeah, my parents are also getting the "The broadcasters signal information has changed, a DTV rescan will start to update this info [yes /no buttons]" on their samsung as well.  I've not had time to look into why or a work around yet....

That can probably be turned off in the services menus
