Hi
I live in central Italy, near the town of Montepulciano in Tuscany, some 90km south of Florence. Several years ago I installed a 2.4m IRTE dish in the hope of getting BBC from Astra 2D, but with no success. I even spent over 500 euros to get an "expert" company to align the dish for me. Still no luck.
Reading through a lot of posts here, I began to realise that I could have a problem with the dish - several of the metal panels were damaged during shipping and at the time I did not realise how important accurate alignment could be. Lengths of fishing line stretched across the dish showed that it was distorted - there was about a 1cm difference between the highest and lowest lines at the center. Some weeks ago, I placed an order for a new 3.7m Prodeline dish which, being glass fibre, should be easier to assemble correctly.
Last month, I finally managed to get a proper ADSL internet connection to my house so I disconnected the 2-way satellite internet that I had been using. This left me with a Channel Master 1.2m wide offset dish that I no longer needed. This moring, as I had nothing better to do, I connected my Invacom 120 Quad LNB (the latest HD ready version) to the existing Andrews feed horn and realigned the dish to 28.2E.
On my Satlook NIT specturm analyser, the frequency specturm seemed at first sight to be better than that from my existing 2.4m dish. So I carefully set up the dish - especially the skew. For the first time I could see some evidence of signal peaks in the frequency range of Astra 2D. So back in the house, I swopped leads to connect the Channel Master dish to the Pace Skybox 2600 and there it was - a slightly pixelated BBC2 England !
A quick check established that I am just receiving tp45 at 10773H. Manually adding the transponder to the channel list gave me BBC 1 London as well. By luch time, the pixelation had disappeared - below is the BBC1 screen shot.
In the house, my Satlook gives a reading of 50.2db for the 10773H transponer using the 1.2m dish and only 38.9db for the 2.4m dish. Bearing mind that the 1.2m Channel Master dish has a published Ku band gain of 42db while the IRTE has 46db, there is obviously a BIG problem with my IRTE dish.
So if the my new Prodeline 3.7m dish has anywhere near its published 50db gain, then I should get about an 8db improvement over the Channel Master. Not only BBC1 on the H transponder, but even ITV and the real nivana - BBC HD. (Well I can but hope).
Many thanks to all the comments and tips that have got me this far.
