I used to see these exact same results when I would setup Wireless pop's on
towers taller than 400Ft. I was able to push the envelope a bit, however
when I saw the issues that you speak of, it was when I had bad crimps, or
sometimes a bad cable all together. Cat5 should be fine for this... if you
figure 12ft risers you are probably cutting it close on the distance but not
going over it.
