Is the new AD DB4e much better than the CM-4221HD? From what I've read, I don't know if it is really worth the extra cost. I know that the CM-4221HD uses nuts that can be tightened, or loosened to do a 'hack', and the new DB4e uses rivets that I've heard can sometimes be slightly loose upon opening the box (recognized factory problem). Right now, I seem to be having pixelation and lock issues with stations below a Noise Margin of +38dB - +36dB. The best I can get is 50% to 65% on those, and that's when pointing directly in their compass direction. I can't see if there is corrosion where the feed lines are riveted to the antenna elements. But the feed lines themselves look quite clean on my AntennaCraft VU-160XR, when looking at it with binoculars.
