This is a great diagram of where the 146.94, 224.8 and 444.2 antennas are located. Due to the size and shape of the KVUE tower, some directions work better than others. In addition, each repeater has its antenna mounted in different positions on the platform.
W5RKN prepared this with accurate antenna installation data. It should be very helpful in understanding where and why these repeaters work. The file is a small PDF that may be downloaded here.
Thanks W5RKN!
