Alan Goss: Digital UK's reception predictor indicates / suggests that reception of PSB3 / BBC HD is not possible from Dover, nor is ArqB / COM6, I only say suggests as reception predictors aren't exactly an exact science.

Alan Goss: The model featured in your link is a much later version than the one I referred to, as witnessed by your model having protection against problems caused by 4G transmissions, this being a relatively recent event that didn't come into the equation until around three to four years ago.
However, apart from that. With regards to you having said that your aerial hasn't moved since it was installed, it most likely hasn't! but the angle the signal is received at most likely has, as in non line-of-sight reception of a nature such as yours, the angle the signal reaches your aerial can change slightly at certain times of the year due to weather etc causing changes in the reflective surface of the terrain, i.e: the summer / winter effect, atmospheric related reasons also playing a role, aerials in many instances having to be turned a few degrees to the left or right to peak the signal again, or in some cases physically moved to the left or right or even up / down.
This is something which has always applied in situations such as yours, but which was not really noticeable in the years analogue reception by this mode being far less critical as far as exact aerial alignment is concerned, the only thing that some viewers might have observed being the picture having developed a slight grainy effect at times.

jb38: Morning jb: Brilliant idea to suggest Alan rotates or tilts his aerial slightly. Richard, Norwich.

Alan Goss: The undermentioned is a link to the older version of your SLX6 distribution amplifier, each of the six outputs rated at 4dB less than the later model featured in your link.

Richard Cooper : Well thanks Richard, but though not exactly "rotate", as that's inclined to suggest altering the polarity, which isn't involved, but to move the aerial a few degrees to the left or right from the angle of 190 degrees that the station is listed as being at from Alan's location.

Thanks, I have rotated the aerial clockwise a few degrees but will have to change the mounting to get any further as the roof angle is bending the reflector (in fact the top rod is now bent). The picture is now OK on normal reception but breaks slightly and drops out at times on HD.
I appreciate what you mean about the reference to 4G on the amp instructions, which I didn't think would have been around at that time, but the picture is definitely the format of my amp, it is a 6X as shown.

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?
