Default Can someone give the correct length of antenna wire need for each frequency?

some repost this info?Thanks in advance...


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...
