With reference to the last post from Peter Baker, why not lower the aerial slightly,or just do a manual tune by frequency and then if all else fails, fit an attenuator (they're cheap enough)?
I live in Grantham, and although not current, I gained my CAI qualification nearly 20 years ago.
A little 'tweaking'can certainly save the customer unnecessary expense.

In reply to JB38s comments of Friday 27 January
We are grateful for your clarification. It is some 20 years since I qualified with the CAI and I am no longer active in the trade, thus it could be said that semantics muddied the water.
Nevertheless, I am content that my interjection may have added to the sum of human knowledge on the subject.

Reception of German Satellite channels in the UK.
My wife (who is Swiss)likes to watch the German channels, so when the closure of Analogue transmissions from Astra at 19.2 was announced I had to act.
I live in Grantham, Lincolnshire so purchased a cheap 60cm Sky dish with Quad LNB and a Philux FTA receiver. Total cost (including delivery) £70.00. Installation (using the existing cable run)took about 1 hour including tuning. Obviously if you want the HD channels a more sophisticated receiver and card would be required.
Glad to answer any questions

Flim and anyone else who is interested in having copies of Brian's excellent articles, I have taken the liberty of copying and pasting both into a Word document (I hope you don't mind Brian).
If you go to my web page (http://www.nigelcory.co.uk/) which is despite the title, just a private site, leave a message on the 'Dream Book' page with your email address and I will send a copy of the document to you.
Regards
Nigel

Ian. You have probably answered your own question. If 'your client' has had reception problems but you haven't, it seems quite likely that there is a problem either with his equipment or local interference.

Grantham
Hello. My location is in NG31 and I have line of sight to Waltham (13 miles). I have been having the same problems over the last couple of days with stations on Mux 2. I have two identical wideband antennae in the attic and the signal strength has always been excellent from both.
To regain the Mux 2 stations on the Panasonic TV, I had to delete and then do a full scan. This worked eventually. The second antenna feeds a Vivanco Pro DVB-T USB2 tuner running into a PC. The cable run on this is even shorter than the one to the TV (about 4 metres).
Using the provided software and selecting Waltham for scanning, the missing stations are indicated by name and frequency (490000) but no signal. When I again deleted all stored stations and scanned selecting 'All UK transmitters', the missing channels were restored albeit at a slightly lower signal strength (sorry, I have no dB readout) but still excellent quality. I assume that the Mux 2 channels are now being received on a sidelobe from Sandy Hill.
I am confused, as prior to the recent changes, all stations were received from Waltham on equal signal strengths. It appears that the Mux 2 is on a slightly lower power output (8KW) than some of the others but Muxes B, C, and D produce excellent results from Waltham although stated to be on only 5KW output.
I have never believed in the received view that matters 'technical' are a matter of logic. There must be gremlins in the area. Although I am of course open to persuasion that I am wrong.

Nigel
