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.
CHARTS OF FEEDLINE LENGTHS: 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:
Antenna Trimming Chart. Use this chart as an aid in trimming the length of your antenna. It gives you an idea of the change in wire length needed to move antenna resonance to a specific number of kHz. Dimensions are for each leg of a half-wave dipole.
This section contains three tables that can calculate antenna shortening factors and antenna lengths, including quarter-wave verticals over perfect ground, half-wavelength dipoles in free space, and long wire vertical and horizontal antennas.
5 cze 2021 · This page contains an antenna calculator for popular types of ham radio HF antennas. Here is a simple antenna calculator for two popular forms of ham radio HF wire antennas: the horizontal dipole and the inverted "V".
