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.
The random wire antenna is probably one of the least expensive, easiest and cheapest HF antennas to use if you have a tuner and you want to get the "most" out of a length of "random" wire without having to pull out that calculator, doing the math, getting the center insulator built or bought, running the feedline, and all the rest that goes ...
5 cze 2021 · Here is a simple antenna calculator for two popular forms of ham radio HF wire antennas: the horizontal dipole and the inverted "V". (Updated June 5, 2021)
This page contains tables showing usable feedling lengths (LF) for 3 different sizes (LD) of antennas. It also shows lengths for generic 600 Ohm line and 450 [400] Ohm Wirmean line. IMPORTANT: ANTENNA MATCHBOX SPECIFICATIONS:
1 wrz 2021 · For quarter wave antennas: apply the change in length directly from this chart. For full wavelength (loop) antennas: multiply the chart dimension by four (4×) and change the overall length of the antenna by that amount. The provided trimming lengths are estimates.
23 sty 2024 · For each band, I will provide a typical wire length for one side of a dipole for the target frequency, which is usually the bottom edge of the band, along with expected variance, recommended starting wire length, expected SWR bandwidths, length of the hanging tails, and an estimate of the change in wire length to shift the frequency by 100 kHz ...
