I have yet to test using the main cable for any HD reception. WIll give updates as soon as I can. Thanks.

Here are the results. Surprisingly using our main cable I got all the HD channels all in good form. Hurray! The signals for HD channels are around 28-29% (no booster at all) and quality varies from
0-36%.
But when I put back the telly in my bedroom with the newly retuned HD channels (HD box), produced horrible results. Quality flicker back and forth from 0-5%. Every 10 sec I got blank screen on all HD channels. Is this the result of the splitter? Do I have to replace it? I am not using any booster. Thank you for your patient.

Dupree: Thanks for the update. I will say though that the signal strength / quality indications given cannot by any means be classed as good considering the relatively short distance that the transmitter is away from you, however I did notice that others also seem to be suffering from reception problems in your particular area, and in your own case this not being helped any with that type of passive splitter you use, as it does have quite a high insertion loss to the extent that its like fitting a 6db attenuator in line with your aerial, so should this be easy to access try by-passing it so that the aerial is feeding directly into your TV, checking what the results are and giving an update.
Regarding the aerial referred to, where is it installed? and are you positive that is facing at the correct angle for the transmitter? that of 151 degrees.
Another thing I would like you to check is that the HD mux channel indicated on the signal strength check screen is actually Ch47, just in case by any chance that a signal has been picked up from another transmitter and not Heathfield.
Finally, as no two brands of equipment have the same sensitivity, I would like you to try the Freeview HD box in both locations using the same channel for the test, as this would also reveal if any fault existed in the connections to both locations, as if not then the results should be the same in both locations.

Dupree: By the way, my reason for requesting that you try by-passing the passive splitter is two fold, insomuch that if your reception gets worse strength / quality wise then that's a positive indication that you are receiving an excessively high level of signal, but on the other hand if reception improves then that indicates the reverse, and this is something that hasn't exactly been determined as yet.
If though reception does improve with the splitter by-passed, then for another test try connecting a short piece of wire of about 600mm (or longer) into the TV's or boxes inner core of the aerial socket and check if any form of reception is possible by doing that, try the test whilst on the BBC.

Dupree: Correction to my last paragraph, "not" should have been inserted after does, i.e:- If though reception does NOT improve with etc.

Thanks for the replies. The results I replied before is for using freeview HD box + LCD TV on both locations (by-passed and split[bedroom]). But if you are suggesting to directly connect it to my telly, my telly only have freeview built in but not HD hence the need for hd box. Sorry If I confused you somehow.
The results clearly shows that I can scan HD channels tru by-passing the splitter but won't show HD on split cable.
My aerial is attached to a long pole connected via our fire escape stairs. we live in a flat area and living on the first floor. Currently it is facing at a bearing of 104°. If I'm going to face it 151 deg bearing, the aerial would be facing my flat's wall directly with just a few meters away from it. Will it be fine if I change the aerial's facing position eventhough it will be facing the wall directly? And for 2 months now there is a scaffolding constructed around the flat for re-painting purposes. Could this be the culprit of low signal reception?
I really appreciate your help. Thank you.

Dupree: I didn't pick up on the fact that you were transferring the TV "and" HD box together to the second location and with that being why I had only mentioned the box, however on looking at your posting on the 21st @ 1.34pm I get the impression that although the aerial goes straight into the passive splitter without having any form of amplification, the coax lead that comes from one of its outputs for purposes of feeding the signal to the living room is boosted at some point? should this be correct then why don't you place the booster in line with the aerial and connect the boosters output into the splitters input? as doing it that way will result in all outputs having the same signal strength.
Regarding your aerial, I suspected that something odd must be applying to your set up as you should (in theory anyway) be getting a strong signal from Heathfield, that said though was the post code given an approximate one? as the location I see, being Croft Road near to The Golden Thai / Hospice in the Weald does not really match up with the description you have given of your circumstances, and aerials around that area would appear to be pointing more in the direction of Crystal Palace or whatever, maybe you could clarify on this point, as me having indicated that Heathfield is located at 151 degrees is based purely on the code having been given.
Of course should the location described be correct, then I can fully understand why the signal strength is so low coupled to the quality being erratic, as although scaffolding can have a bad effect on reception, but the fact of your aerial being so far out of alignment will be compounding the problem, and so if you can easily access the aerial you should leave the box set on its signal strength check screen whilst its tuned to an HD channel, then loosen the aerial clamp and try swinging the aerial around to approximately the heading given irrespective of where its facing into observing the results whilst doing so, should this be possible.

I have some good news. After being frustrated with the signals and all, I decided to rewire and re-positions all my cable connections and even moved my television to different spot. You wouldn't believe what happen next, I got HD reception in my split cable connection. Signal/quality varies 26-28%/54-65% on all HD channels. I didn't place any booster at all. Thank you all the support. Sorry for the trouble.

My TV is showing no signal on all channels I live in a flat and all are the same. I have tried re tuning and that just shows no channels are available!! This has been like it since last night. When I switch on my BT Vision box it is exactly the same, although I can watch catch up TV without any problems. Any answers! I am not sure exactly where the arial is.
