This is my set up (as far as I understand it).

1. Signal come in from sky dish into TV huh in garage.
2. Signal goes into lounge where sky box is. I have a modulator there.
3. Signal returns to garage TV hub
4. Signal goes to bedroom.

The signal in the lounge is perfect. In the bedroom there is a lot of "static" like an old bunny ears signal. The TV is fine as if I play DVD on it the picture quality is perfect.

I assume the signal is loosing strength as it travels through the house.

How can I fix this issue?

I assume you just have a regular UHF modulator and the poor picture quality is simply a result of tuning in an analogue modulated signal fed from the composite output of the box.

I think so, the modulator was given to use when sky was installed. Should I check something to confirm this?

Sounds like everything is working perfectly as intended. An RF modulated signal is the worst possible signal type. If you want better picture quality you'll need to move to something like a DVB-T modulator and HDCP stripper and/or HDMI over cat6 cable.

Lots of places. HDMI over cat6 adapters can be sourced from virtually anywhere. Jaycar sell them if you want to buy locally.

As for DVB-T and HDCP strippers you're starting to look at probably ~$500 minimum for a good solution, with cheaper soluitons from the usual sources in China if you like playing.

Jay at is close, how does this work?

Does the signal go from sky box to a hdmi/cat6 box then into cat6 port? When happens at the other end? How doe cat go into a tv hdmi port??

Can you provide a jay car link?

So if I understand this correctly I can take my HDMI output from sky, put it into Cat6 cable and run it to my tv in another room.

Correct??

If so how do I take the signal from sky box to the local tv if the hdmi cable is going into this thing?

One of these might be a better way to go.

or get Sky Multiroom.

Yes that's now it works. You have an HDMI connector at each end of the balun.

If you want to plug your local TV in as well you'll need a HDMI splitter. Once you can get these from all the usual sources of electronics online, or Jaycar or good local electrical wholesaler if you're wanting something local.

Look again. It does Digital/Analogue, Satellite and Backfeed Digital or Analogue distribution around the house.

Just connect UHF Antenna, Sat Dish and Sky Modulator to the 3 inputs and get all of them at all the output ports.

Or call sky.

If the signal is fuzzy it could be the modulator is tuned to a freeview frequency.

It could be the signal comes from the modulator back to the garage down the wrong line OR

A failed splitter

a failed connector

Honestly I would get SKY out to have a look at it and go from there. Make enough noise and its usually free.

None of that changes the fact it's a composite feed into a UHF modulator. This is the worst combined with the 2nd to worst inputs for video quality.

Correct - it is the lowest quality method of TV signal BUT it should be perfectly watchable without static/grain if running correctly.

Is it split in the TV hub OP?

If so disconnect splitter

- if good = win.

- if no good, connect tv direct to modulator = if bad replace modulator (ring sky = free)

If good, connect TV at hub

- if bad fault between lounge and hub

- if good then fault lies between hub and bedroom (likely connection at one or both ends)

The usual problem is that the output from them is very weak, and people try combining with off air antennas. Add to that the large use of the band for digital and the use of the top of the band for LTE now and there is a great chance of interference.

What channel is the modulator on? The sky ones usually have that on LEDs on the front. Check that against the list of freeview channels in the area you are in, and check that its not over 50 which is where LTE starts.
