Since there is an infinite number of frequencies, how about we do this the easy
way instead of posting infinite wire lengths to match? :-)
To calculate the length, in feet, of a half-wave dipole antenna simply divide
the number 468 by the frequency in MHz.
To calculate the length, in feet, of a quarter-wave vertical antenna simply
divide the number 234 by the frequency in MHz.
It should be noted that these equations include a factor to account for end
effects and is generally not as accurate for VHF/UHF antennas.
Hope this helps...
