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.

- Random Wire Antennas - Best Lengths To Use For Random Wire
In Jack's own words.... "Here's the word on random-wire antennae." Presented for your consideration by Jack, VE3EED. The table below represents half wave lengths and multiples that you DO NOT WANT TO USE! You have to stay away from a half wavelength on any 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.
Table shows typical SWR relative to installed wire length. SWR will vary based on topography, proximity of nearby structures, configuration of the antenna wire and choice of ground or counterpoise. For best results, use the longest wire shown on the table that will fit your installation constraints. Installing the antenna wire as an Inverted L ...
This page contains tables showing usable feedling lengths (L F) for 3 different sizes (L D) of antennas. It also shows lengths for generic 600 Ohm line and 450 [400] Ohm Wirmean line. IMPORTANT: ANTENNA MATCHBOX SPECIFICATIONS:
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) The Antenna Calculator. for. Half-Wave Dipoles. Enter your desired frequency (MHz) of operation (i.e. 3.55).
The "Best" Random Wire Antenna Lengths Randon wire lengths you should and should not use! 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
