Interesting, I remembered my phone has a compass and tried various angles with the Sony on Channel 4 (following the F1):
190 deg: 80% quality, 46% strength
195 deg: 99% quality, 50% strength
200 deg: 99% quality, 54% strength
205 deg 100% quality, 58% strength
Can't go any further due to the roof but seems to be a fair way off the nominal 190 deg. (Have now broken the top bar of the reflector trying to bend it further, hopefully no real detrimental effect).

(sorry, last post seemed to go in a new thread, hope this will work).

Alan Goss: As you have now successfully achieved 100% quality @ 205 degrees, I would say that even although you might well be unable to turn the aerial any further because of the roof, your likely to find that you are only the proverbial stones throw away from the signal being peaked anyway, therefore I would be inclined to leave it at that for the time being.

That said, I feel that your reception would benefit (as far as reliability is concerned) by running at a slightly higher strength level (80%) with the aid of a low powered booster, the output of same fed into your distribution amplifier, but though it all depends on the maximum signal strength levels received from the other multiplexes with your aerial in its present position.

By the way, I wouldn't worry too much about the top bar of the reflector, as its most unlikely to have made any difference to the situation.

Another point I meant to include in my previous reply, is that in situations such as yours its quite common for multiplexes to be received at different levels even although they are all radiated at same power level, which in the case of Heathfield is 20Kw.

Thanks.
What would be a low powered booster? I was thinking of something like an SLX2 between the aerial and existing amp. Is that too powerful?

Alan Goss: No, as either that model or alternatively the single port type referred to in the undermentioned link should be perfectly OK for this purpose if installed between the aerial and the existing distribution amplifier, the variable output being adjusted to a low level to start off with then advanced as necessary to lift the signal strength up to around the 85% or thereabouts, that is if achievable!

The qualification on using this or any other variable booster, is to ensure that the output level of the multiplex already received at the highest level isn't lifted to above 95% or so.

Now put an SLx2 between the aerial and the existing SLx6x amp (needed the mains lead to the socket). I now have 100% quality and 98% strength on the reference Sony but needed the SLx2 turned up fully to get that.

Odd thing is there is about 1-2second delay between the Sony and Tosh TV's on the ground floor. How can that happen on the same amplifier?
Thanks all for the help.

Answered my own query - Sony was on standard and Tosh was on HD, obviously gives a difference in output, presumably due to processing time or something. They are in sync on the same format.

Alan Goss: Re Answered your own query (six minutes between postings), Yes, that's exactly the reason.

On the subject of signal strength, pleased to see that the addition of the SLX2 has had the desired effect, although I would back its gain control off slightly to give around 90% or so strength, this action being as a safeguard against the possibility of any slight fluctuations in the signal received (which can be up or down) intermittently taking the strength over the 100% level, as this "might" result in the occasional glitch being seen on the picture.

By the way, 100% strength on a Freeview receiver corresponds to the maximum dB level that the device is capable of operating at without being overloaded, the problem being that any intermittent rises in dB levels above this maximum will still be indicated as 100% strength, this being why its always advisable to keep it a tad lower in order to accommodate for this possibility.

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.
