Thanks for the info on spacing Rabbit. The chart is slightly confusing, but if I'm reading it right, it looks like the optimum vertical spacing is 0.67*lambda, and the optimum horizontal spacing is 1*lambda, where lambda is the wavelength of the "lower-channel antenna". Since my UHF antennas are obviously both the same, I guess I'll take that to mean the the lowest frequency in the UHF band (Ch14 = 473 MHz), so my lambda is 25-inches. The spacing to optimize reception of WFFF (Real Ch43 = 647 MHz) should be based on lambda=18".

At least those are some ball-park numbers to start with. I'll try vertical stacking first because it is easier to implement. I notice that 0.67*lambda for Ch14 is 16.5". That seems pretty close, but we'll see if it works. The recommended vertical spacing is even closer for Ch43 (0.67*lambda = 12.25").
