I would suspect that antenna placement, and possibly considering a different
antenna design, would make a huge difference. Look in some radio books for
things like Yagi designs. Give you much more range, but also make the antenna
very directional. I use a lot of radio communications for industrial work, and
things that can be 'non obvious', are interference sources, things _behind_
the antenna can have a suprising effect, placement etc.. The actual design of
the antenna has a massive effect, but then you start looking at things beyond
the scope of simple 'movement' :-)
