Same problem here on the East coast Bob. Trees are a major PITA, I have 
a large walnut tree that blocks my view to the east and Southeast, and 
last night I could barely make out the beacon through the trees, but my 
setup pulls down a solid S7 or better then the satellite is in the clear 
at similar squints. Trees even affect  TVRO class AO-40 setups 
profoundly, so the only alternatives are to find a location in your yard 
with fewer leafy obstructions to set up your dish, put the works on a 
tower so it shoots above the trees (but Douglass Firs can get huge), or 
get out the chainsaw.
