Dipole and Inverted Vee Antenna Calculator. Sufficiently accurate for wire antennas up to 30 Mhz. The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters .
The program will then calculate a Radiator Element length of 31' 7-3/4" (9.64 M), a Mast Height of 22' 10-1/4" (6.96 M), and a Horizontal Space of 45' 8-1/4" (13.93 M). The calculated information in the example is effectively the ideal setup for an Inverted-V.
This downloadable calculator will provide you with good starting measurements for a basic ground plane, Inverted V or standard Dipole antenna. The graphics below are "screen shots" taken from it.
5 cze 2021 · When each side of a dipole slopes down from the feed point, it is commonly called an inverted V. The inverted V results in: A more omni-directional radiation pattern than that of a dipole. A lower resonant frequency for the same length of wire as the dipole.
Calculator to design Dipoles And Inverted Vees HF Antennas. Enter the formula for the antenna calculation. Divided by Freq MHz. Percent smaller for the Inverted Vee.
5 lis 2024 · The dipole / inverted vee antenna is one of the most effective wire antennas you can use. Enter The Values For The Dipole / Inverted Vee Antenna Calculation Enter Freq with three decimal places ie: 3.900, 7.263, 14.300, 145.390, etc... Full Wave = 984 / Half Wave = 468 / Quarter Wave = 234 Freq MHz Percent smaller for the Inverted Vee
Inverted Vee Antenna. The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna is: 143 ÷ freq (mhz) = Length (metres). The inverted Vee antenna will be shorter by 2 – 5% depending on the angle from horizontal.
