Can't get HD
aligned with tried manually tuning our Samsung UE40D5000
Crystal palace - HD on - - (545.8MHz)
- HD on - (682.0MHz)
- HD on - (626.0MHz)
and still can't pick up HD everything but
Maps suggest we are in a black hole for except perhaps Bluebell hill. Any suggestions eg realign aerial to Bluebell Hill and retune - but that means getting on the ! Don't want ! anything else we can do eg getting a better signal ?

mike: The Samsung UE40D5000 is fitted with a DVB-T ( definition) tuner. To receive the you will need a Freeview HD box incorporating a DVB-T2 tuner.

Thanks KMJ - seems some descriptions do say it has an HD Tuner but others says it lacks an HD tuner. I guess that explains it.

Is the CP currently undergoing servicing or something. The in TW15 is terrible for a transmitter. And, before you suggest it, I have had good to fair , before. Do I need an attenuator for a too high signal strength or is the signal just lousy ?

Hi,
I have fitted a brand new 48 element High into my . I am pointing to from BR7 6PT. All other aerials are pointing in same direction.

I have a 2-way f-plug splitter just after the aerial serving 2 rooms in my flat using new grade .

One TV will only tune into the BBC (new Sony) and the other TV (Samsung) will rarely tune to any channels, but occasionally picks up the ITV group. Never gets BBC though.

Someone said to me that my may be too strong being so close to Crystal Palace and of course a high gain aerial would not.

Anyone offer me any trouble shooting please apart from the usual checks of connections etc.

Thanks
Bill

BillNick: On the face of it, unless the area is known for issues such as because there is a building in the way, then too high a signal level does appear to be a likely possibility. Generally speaking, aerials used for former should be fine.

See:

Freeview signals: too much of a good thing is bad for you | ukfree.tv - 10 years of independent, free digital TV advice

If the high- is a one, then it won't be so "high" gain on the used by Crystal Palace. This is because the gain of an aerial varies across the range of frequencies/channels and for yagi types (which it is likely to be) the gain is always lower on lower channels.

Thanks Dave.
I have looked into the levels using the manual tune function on my telly.
CH22 and CH23 are coming through over 75 level and 100 .
CH25 wont tune
CH26 is at 60 level and zero quality
CH28 is under 10 level and around 20 quality.

Any suggestions having seen these results? I am using a sideband high pointing to . (51.4529,0.0972)

BillNick: The problem could be the position of the is one where the is messy, that is subject to multiple reflections which the is unable to decode. Try moving the aerial a short distance to either side if space permits. Also try pointing it the wrong way, so the signal is received from behind the aerial and observe the signal strength/ for each mux.

BillNick: You could try the suggestion by KMJ,. Or it could be too high strength, in which case you need an attenuator.

Thanks guys. I think I may have 'messy' . I woke up this morning and BBC, which was up to 100% signal last night, was only at 40% level and under 10% this morning!

Is the only thing I can do here, move the ? Would it to swap out the aerial I got to a dedicated A group aerial?
