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.
Loop antenna lengths are based on using 1005 / FMhz = total loop length in feet. As with any antenna, lengths should be cut longer than formula results and then trim as needed for best swr. The chart covers all ham bands from 160 meters through 2 meters only.
5 cze 2021 · The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole. The results are conveniently displayed in inches, centimeters, feet and meters. This formula to obtain the length of a half-wave dipole antenna will give a good ballpark value to start with.

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.
7 paź 2024 · Use this calculator to find the dimensions of a Dipole antenna [1] designed to operate at a specified wavelength or frequency. A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end.
This tool calculates the physical dimensions of a 2 meter dipole antenna. At 2 meters, the dipole length (L) is 3.12 feet. The length of each element of the dipole (l) is half of that at 1.56 feet.
