Thanks to "Commsprepper" for this handy, useful chart of VHF/UHF frequencies for amateur radio, MURS, Marine, and GMRS services.  The chart contains specific lengths for antennas covering 136 mHz through 520 mHz.  Use the formulas on the chart to compute the exact length of a 1/2 wavelength dipole antenna. You can cut the measurements in half for a 1/4 wavelength vertical antenna.  I have a similar chart mounted on the wall of my ham shack for easy reference.
