free to air satellite

Hi
I have just installed my own satellite dish with a monoblock LNB so I can get astra at 19deg and hotbird at 13 deg. My problem is I cant get a signal for the astra, the hotbird is grate. I contacted my local installer, he came with his yellow horizon satellite finder, he got a grate signal for hotbird but no signal for astra. he tryed a different monoblock LNB without success. Any help will be very wecome.

are you sure there is nothing blocking the signal, ie trees?

How big is your dish? This site says that generally an 80cm dish is required to achieve this.

What did the local expert say?

HI
no there is nothing in the way.Thanks.

Hi
Yes its a 80cm dish.He cant understand it. I also had a SKY installer round and he had no luck,the two satellites are only 6 deg apart.

Well the way that they work is that it is aligned to one satellite at say at 13 deg and the monoblock should then get the second satellite at 13 + 6 = 19. Therefore if it isn't aligned to the correct satellite on the first one i.e. 19 + 6 = 25 deg if you see what I mean. However I would assume that your expert would know all that!

Thanks espresso.
Thats what I cant understand I have got a grate signal on hotbird and have tuned in over 1100 channels at 13 deg east but when he trys to tune in astra 1 at 19 deg east he gets nothing.

The LNBs switch using DisEqC (22kHz tone) - have you checked that your receiver is set up for this?
If the 'expert' has tried another LNB without success & there's nothing blocking line of sight & the dish is aligned correctly, then he's either tried another faulty LNB or he is having trouble setting up the DisEqC command on his Horizon meter - if I remember correctly, it's not enabled by default on these meters & you need to set it up each time.

I'd try a normal LNB on the dish & re-point it at 19.2 to test & then 13 just to eliminate line of site issues.

I have seen a similar problem to what mcfisto is describing with a monoblock LNB - it was fixed by setting Hotbird to Diseqc A and Astra 1 to Diseqc B in the settings for the receiver and then running a scan for channels.

Thanks
