ME10 1DB, using Bluebell hill
Do you have any idea why our HD signal on C40 keeps going to "No Signal" on the TV screen on all the HD channels, All the SD channels are OK. We have a Panasonic DMR PWT420 recorder & within its set up you can see the signal strength & the signal quality levels moving around quite a bit & they will fall away completely for a second or so then recover. Our aerial man is a bit baffled. Our aerial is a wide band high gain & about 20 years old, it is already fitted with an amp.
Why is it only affecting the HD. Annoying, before the switchover last year it was OK. The aerial man has tried various filters & attenuaters

Bert: I wonder if it could be traffic on the M2 and the A249 which both cross the signal path. Or indeed it could be something else in the signal path, such as vegetation.

You don't have line-of-sight to the transmitter:

Perhaps this is something that is out of your control which is why the various attempted fixes have not worked.

Different frequencies are affected by objects along the signal path in different ways which can result in not all channels being received at the same strength at a single location.

I did wonder about the line of sight problem, I can't view the terrain plot as i'm using IE8 on XP,
Aerial man is returning on Friday with an E group aerial & I will tell him to put it up on the chimney using the existing pole

I clicked through to the megalith pages & fiddled about with my location to get it closer to the home. I still had two hills in the way but pushed the aerial up to 15 metres & it just clipped one up by the M2. So I'm out with the measuring tape tomorrow to get an idea of the height of the chimney, plus pole. I will tell the young aerial chap of the findings.
Thanks

Bert: It doesn't work on a thin laser-like point! Anything within the first Fresnel Zone may affect reception:

Fresnel zone - Wikipedia, the free encyclopedia

Also, there are objects on the ground and terrain plots only sample the ground height at intervals, so it may not be totally accurate.

Megalithia shows the first Fresnel zone by a pink line:

Adrian: The DUK prediction is for good reception on all muxes from Bluebell Hill and Crystal Palace using a suitable aerial. Firstly is your aerial on Bluebell Hill intended to receive C54? A group "E" or wideband would normally have been fitted for analogue reception, however if your aerial is a group "B", identified by a yellow stopper at the end of the boom, it would be somewhat less efficient at picking up C54. Trees or a tall building obstructing the signal path could also result in C54 being received at lower strength. If the aerial happens to be positioned in a null for C54, slight repositioning (raising, lowering or a short distance either side) might be needed to improve reception. Interference blocking the signal is another possibility, either an analogue signal from the RF modulator of a Sky box or VCR set on or near to C54, or interaction with an HDMI cable, which would need repositioning relative to the tuner or aerial fly lead to overcome such a problem. Check that all connectors are in order. One other thought, if a communal aerial is in use there might be channel filters which require adjustment to let C54 through. In that case the landlord or building management company would need to be contacted after getting confirmation that neighbours in the same block were having a similar problem.

My existing aerial & 3 metre pole have been refixed to the chimney gaining about 5 metres in height from its previous position. Since then we have not experienced any temporary loss of signal on the HD channels. The aerial man then said that we had 75db of signal with our existing masthead amp, he tried again but without the amp but the db's were too low. The chap said that the existing signal could be too high under certain conditions, so we now have a variable amp mounted in the loft set to give us 60+/-db. 3 TVs are off this one aerial, the bedroom & kitchen tvs are on one cable via a splitter instead of a small booster, this booster was not necessary with the good signal now from the repositioned aerial.
So, height matters in our post code.
Thanks for the advice

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
