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.

Simple Ham Radio Antennas--Antenna Information for Emergency Communications

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=nNXvuv83ZNc. This is post #930 in a continuing series of Simple Ham Radio Antennas. "Commsprepper" has offered a helpful, handy, and informative guide to the major frequency bands and users in the VHF and UHF bands.  Keep a copy of this guide near your rig for reference.  You can make your own chart as well by using the simple 1/2 wavelength antenna formulas given in the chart. The first formula is for the length in meters.  The second formula is for the length in feet.
