Tried flip pol on just one end instead of on both at the same time? On the tilt sounds like your hitting strong side lobes which sometimes can give better gain the main but the side lobes are usually very narrow so little movement can change signal a lot. Consider the antenna probably has a 6 deg beam that means 8/2 is just the edge.

WAS: Candy We switched the polarity -- made no difference at all. Just scanning for other radios in the area (or at the same site) the signals look a little low too. Pigtails are from different shipments about 2 years apart on either end. But the jumper cables are the same. I wonder if we got a bad batch of cables. But then... that doesn't explain the weird alignment.
