Gentlemen I am 30Km North of Dublin on the East Coast of Ireland. I am interested in maximising my reception of Viasat on Sirius. I am using a Channel Master 1.8M offset dish with an INVACOM SNH-031 0.3dB Universal LNB seeing 33E to 30W. My receiver is a DM800 PVR(Gemini 5.1img), at present I have PL Xtra channels(11.747V) 24/7 except in heavy rain/snow. The strenght of the channels signal varies by 25% over the course of the day. Whereas 11.727H comes in for about 4hrs a day as best I can log it. The same is true also for 11.997V and 12.092V. These are examples of a pattern. Should I be seeing more and what would reccommend as a wat to improve reception in my home? All thoughts most welcome.
