I've answered my own question!! With some testing, I found the 264 will perform better on the 147.36 system than the 224.. at least VSWR-wise.
So, I'll use my 264. Question still remains.... Mounted on the side of a water tower, what is the best pattern of the 4 bays? Omni, directional to the tower, directional away, or bi-directional to the side? THANKS! 73 Jeff - N5VAV
