To get the half wave length in feet, use 468/f, where f is in MHZ.
The 300 / f / 2 equasion gives you the half wave length in meters.

Subject: half wave length height equation
Group,
I remember QST had an article on how to figure the optim height for a
horizontal antenna, and of course I can't find it at the moment. I am
trying to remember the equation to figure out half wave lengths.
Does the following sound correct?
(H (in feet)=300/f (in MHz))/2 ?
With the recent conversation about verticals I want tofigure out the
optim height to hang a pair of G5RVs.
73s,
