If you are receiving crap at a low inclinastion with a low gain antenna,
you will receive "louder" crap with a high gain antenna at the same
inclination. However, you are approaching an ideal situation with
regards to signal routing. Further in this thread, Brian will mention
that twice the height gives you twice the signal. While it doesn't
exactly work out like that in the real world, it's a close approximation.
Before you factor in any other variable, consider height. Where is the
highest place I can place this antenna *reasonably*? That is the
foremost question on my mind when approaching a new location. The FCC
rulings supersede any and all HOA verbiage regarding antennae and allow
you the ambiguous 12 feet above a structure in the US. You won't know
what you can achieve until you try what the law permits, if needed.
Dealing with crusty neighbors is a separate and totally OT subject for
this list. Often humorous, but still OT.
