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.
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 .
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 · 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).
5 lis 2024 · The caculations are based on 1/2" diameter copper pipe. A choke very close to the feedpoint (within 3-4 inches) is highly recommended to prevent RF from heading down the feedline into your rig. For the 2-Meter band, four turns of coax at 5in diameter should suffice. Dipole / Inverted "V" Calculator.
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. Each leg of the dipole is feet.
A 50 Ohm coaxial feedline is recommended for Inverted V antennas. It should also be used for dipoles at lower heights. The antenna feed-point impedance for dipoles approaching 1/2 wavelength in height can rise to near 72 Ohms, depending on installation.
