I've since discovered after leaving the HBU22 in place for now a multi path problem. While I didn't have one with the MXU 59 with the pre amp, Super G 1483 with the pre amp or even the U4000 with the pre amp, I am seeing the picture break up from time to time on a couple of channels now. Have had each antenna pointed at 15 degrees and situated at about 17 to 20 feet above ground.
It is my understanding that Yagi's are usually good at rejecting multi path signals in urban areas like I am in. Same with the 8 bay antennas. 4 bay antenna's supposedly are not good for rejecting multi path based upon what I've read due to their wide reception pattern yet the U4000 worked very well here.
Could this problem with the HBU22 be due to the fact it is a much shorter Yagi with less elements than the MXU59?
