Upgrading Quad Lnb ?

Can anyone suggest a good quad lnb and
dish upgrade for sky + because my signal is weakening month by month as the
surrounding pine forest grows,and i'm pretty sure I'll be wasting money swapping to sky hd unless I can get better signal strengths, and I can't fell any trees
Cheers

 

A new dish and LNB will not help, it is your line of site that is at fault. Can you not raise the dish higher.

 

I could get the local installer to put up a pole on the chimney breast.Not sure how high I could go before movement became a problem. trial and error iI suppose

 

Getting a bigger dish will help a weak signal ,the sky mini dish looks nice but is poor, i used to loose the signal quite a lot in the rain.
