Since 468/FMHz equals a 1/2wave in FEET;
468 x 12" = 5616   5616/FMHz equals a half wave length in inches.
5616/2 = 2808 which is in effect the same answer for 1/4 wave measurement you 
would get with all of that long mathematical stuff you went through.
When I want to get to the nitty gritty without a bunch of BS jacking around 
with a bunch of formulas AND since I usually work only in VHF/UHF, this is 
what I use...

I forgot...but it works for me...my GP's are all less than 1.2:1 over a whole 
bunch of frequency.
... Have a nice day    Unless you've made other plans!
