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 .
A standard dipole, at an appropriate height, will have a feed impedance of around 70 Ohms. Lowering the ends to ground, in the V configuration, reduces the feed impedance to near 50 Ohms . This can provide you with a better match than a standard dipole.
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. Your dipole's total length is feet.
Dipole and Inverted Vee Antenna Calculator Sufficiently accurate for wire antennas up to 30 Mhz.
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
