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.
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.

Introduction. An overview of common ham antennas for portable, base and mobile use, geared towards the new ham. Answers the (BIG) question of, “Now that I’ve got my license and I bought this Super Whiz-Bang radio, how do I get this thing on the air? Introduction. Remember that frequency is inversely proportional to wavelength.
5 lut 2021 · I want to upgrade the stock antenna on my Baofeng uv-5r for which I mostly use the 2 meter band. The quarter wavelength for this band is about 19.2 inches, but when I look for antennas, they are typically 15.6 or 7.5, or some other seemingly random number of inches.
26 lut 2017 · Antenna length goes hand in hand with the frequency you desire to transmit on. The higher the frequency, the shorter the wavelength. Most commercially available antennas come in length equivalent from 1/4 to 5/8’s of a full wavelength.
