TV in kitchen - boosting signal from Sky Box upstairs

[Yex 450]

I am going to upgrade the TV on the wall in the kitchen to a 1080p 32" of some sort in the near future, possibly a 40" as weights of these appear to have dropped significantly in recent years. The current (very old) 28" TV is not HD and is receiving it's signal via a reasonably long coax cable of about 30 feet from a Sky HD box upstairs which passes through the walls so is not able to be changed. The picture is poor as I would expect with a Sky HD signal going into a non 1080p TV and a long coax cable run. The signal coax cable comes out of the Sky HD box and into a signal booster before about 25 feet of the run to the TV in question.

Before I buy the new TV is there any way I can improve the signal quality of the set up I have, or will it improve once a 108p TV is at the end of the coax cable?

Happy to consider all options apart from inserting a new cable into the walls for obvious reasons

That output doesn't support HD.

Save yourself some money on the multi-room (if you have it) or pay £12 a month more and get SkyQ They were offering a free tv with upgrades before xmas (Looks like its ended now :-(, hang fire for an offer if you can.

LG OLED TV's come with a years Sky TV for free so that might also be worth a look.

SkyQ silver box in the lounge then a wireless HD box in the kitchen. you can watch separate channels and it will be in HD.

You can get an hdmi to rf modulator

This will present the sky picture as a free view channel at the kitchen end.
The TV must have a free view hd tuner built in.
You will also have to split the hdmi output of the skybox, with one lead going to the local TV and one to the modulator

You can get 10m HDMI cables.
I've got a 7m and it looks fine to me (HD PVR - HD TV).

Cheers for the input guys, I should have known that I wouldn't be getting HD in the kitchen via coax cable I am thick sometimes

I will almost certainly go for a new LG screen in the kitchen and then take up the SkyQ offer available as the cost to upgrade will be minimal.
