Chart of Common Frequency Bands. Basically the frequency bands each range over from the lowest frequency to 10 times the lowest frequency. Antenna engineers further divide the bands into things like "X-band" and "Ku-band". That is the basics of frequency.

2.1. Antenna length based on the following formulars: 1/2 λ dipole (feet)= 468 / frequency in Mhz. 1/2 λ dipole (meters) = 142.65 / frequency in Mhz. Full wave loop (feet) = 1005 / frequency in Mhz. Full wave loop (meters) = 306.32 / frequency in Mhz. Cut wire slightly longer for connecting insulators and pruning. 22-Jun-2007 09:30 AM.
One aspect in antenna selection is knowing the intended test frequencies and then selecting a matching antenna. Not all antennas are created equal, and when it comes to frequency different antenna styles perform better at some frequencies and not at others.
When selecting an antenna, the range of frequencies that will be transmitted or received as well as their bandwidth should be considered. Some antennas are designed to operate over a narrow range of frequencies while other antennas are designed to operate over a broader band of frequencies.

A fundamental list of antenna theory concepts, an antenna basics menu is given here. Topics include directivity, polarization, bandwidth, impedance, frequency bands, all things necessary for an understanding of antenna theory, antenna basics and antenna fundamentals.
Here is a handy chart for determing 1/4 wave verticals, 1/2 wave dipoles, and full wave loop lengths. All antenna lengths in the information below are in feet and are the results based on the standard formula of 468 / FMhz = total length in feet.
