Hello everyone and thanks for this forum.The installer is coming 5-11-07 to replace my 3 lnb dish. My zip is 30215. I have a narrow clear view of the southern sky thru some trees. The 3 lnb works great. How much different is the 5 lnb azimuth? My friend tried to upgrade and they said his trees blocked the reception even though he had directv for years. Thanks for any advice.
