Joe,
Making and working with a Phased array is also on my to-do list but I plan on building the phase box. For now I want to play with a vertical beam and using the planned operarting frequency times 1.05 gives me the resonant freq for the reflector provides me the information that I want to use when adjusting the reflector with my MFJ259.
My thanks to everyone that replied. Being Mathematically Challenged (not really) I needed confirmation that I was on the correct path with my math :)
