Simple Antenna Length Calculator

Simple Antenna Length Calculator

Desired Resonant Frequency:


1/2 wave dipole: 1/4 wave whip:
Length in inches
Length in feet
Length in meters


If you want to do it the hard way. The formula to figure the length of an antenna is:

234/frequency in MHz = length in feet

Remember to leave a little extra length to the wire to leave room for adjustment. Trim it down in small increments using an swr meter or antenna analyzer for best results.
