[BC] FM bays

[Milton R. Holladay Jr.]

Never use an odd number of bays. 6 works well, normally.
Use a pole mounting, if possible. Avoid mounting on tower with long 
diagonals like the plague (some Centrals were 3 or 4 feet.).
Go to ~400' HAAT (slight power reduction), even if terrain is relatively 
flat..
A new Dielectric, or even ERI would be nice.

Why do you have .75 spacing ????
