Problems with quality signal

[antoniodarimini]

Dear friends,
I'm sorry for my bad English.

My problem is that with my decoder I se everything well at the morning and afternoon.

At night time quality become bad and I see just Premiere.

I live in Italy - Rimini.

I've dual feed astra-hot berd with LNB Humax.

Hoping to solve my problem.

Kind regards,
Antonio

It is not uncommon that some satellites have weaker signal during night. Probably caused by loosing solar power and switching to batteries.
But if you are loosing signal on all channels then it is probably something else.
It should be either lnb, coax cable getting faulty due to temperature change between day and night, or dish not aligned properly. So I'd suggest looking at all those things. Probably best to have someone specialized take a look.
