2.4GHz and Vhf/Uhf Dual Band Antenna Mounting distance

What would be the appropriate distance to mount a 2.4 Wifi antenna away from a Vhf/Uhf dual band antenna, where I won’t fry either the radio or wifi card? I was hoping that less than one foot would be good enough, since the bands are far enough apart.
mounting distance...

18 or 20 inches would be safest. Theory calls for a quarter
wave on the lowest band which would be 18 inches at 155
mHz. The "rule" comes from VHF/UHF installs, but I'd still be
cautious.

u usually use the rule of thumb to make shure that they can't touch eachother.

Tom is correct, and I'd also add that the closest frequency should also be the farthest antenna as well, if only to minimize stray inductive coupling.
Same goes for cable routing as well...but not that critical though, but it sure can't hurt.
