Ham Radio HF/VHF Antenna Lengths Chart. 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.

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.

Antenna length are VERY important to two-way radio range. When we ship you an antenna, it is pre cut to "Mid" or 151.625. If you are using a higher frequency or would like to do some additional tuning, you can reference these cut charts.
VHF ANTENNA CUT CHART This antenna has a power rating of 150 watts. This antenna does not require a ground plane, and has a VSWR of less than a 1.5:1 with a 50 ohm impedance. The connecting cable can be RG-58, if the run is less than 20’. RG-8X is recommended for runs in excess of 20’. The antenna whip should be trimmed
the length of the spring from the overall whip length as shown above. 2. If using a black coated whip, for proper electrical contact with the antenna, remove the black coating from the portion of the whip which goes into the antenna ferrule (cone). NOTE: 1. If using a spring, deduct.

Antenna length is based on the following formulas: 1/2 wave dipole (feet) = 468 / frequency in Mhz. (1/4 wave, use 234 / frequency in Mhz) Full wave loop (feet) = 1005 / frequency in Mhz: Cut total wire length slightly longer for connecting insulators/pruning as needed for lowest swr.
