Coaxial dipole calculator. Place a 1:1 Balun on the Antenna end of the Feedline. 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 . Although this design is not ideal for a 'pipe antenna' it is ideal for mounting in any antenna mast. Feb 21, 2026 · An efficient program to calculate dimensions of coax dipoles, or bazooka antennas considering velocity length of different coax cables. A page in french dedicated to the double bazooka antenna, with a short history of this antenna model and main characteristics including a comparison versus the dipole antenna and formulas to determine elements size. The collinear dipole antenna consists of two or more 1/2 wavelength sections separated by a 1/4 wave phasing stub in the form of a coil. Calculate the required dimensions for a coaxial collinear antenna construction for any given frequency. It'll also provide you with your antenna's corresponding wavelength value and the option to use an adjustment factor [k] calculated using your dipole conductor's diameter. Design half-wave dipole antennas with our free online Dipole Antenna Calculator. For example, a dipole cut for 7. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. The Folded Dipole The Folded Dipole is not used much amongst Radio amateurs, probably due to the fact that this antenna uses twice as much wire as a single-wire dipole Rf Directional Power Meter A wide dynamic range power meter using a directional coupler, AD8307 Log Amplifier and arduino microcontroller Free Online Engineering Calculator to find the Dimensions for a folded dipole. Unlike the coax collinear, the dipole version requires a ground-plane to operate. The inverted Vee antenna legs will be longer by 2 - 6% from those of the horizontal antenna depending on the angle. Enter the formula for the antenna calculation Divided by Freq MHz Percent smaller for the Inverted Vee Your dipole's total length is feet or meters Each leg of the dipole is feet 6 days ago · The measurements below are for building a simple Dipole Antenna. 0 Mhz will also work well on 21 Mhz. Jul 4, 2022 · Don't forget to rate the application… The calculator calculates the dimensions of an alone dipole and is completely unsuitable for calculating the dipole dimensions of a multi-element antenna. On-line antenna designer. The inverted V antenna more closely matchs the 50 ohm coax than does the standard horizontal dipole, so your swr may be lower compared to a horizontal dipole fed with the same 50 ohm coax. Both metric and English units of measurement are supported. You may change this number if you know of a better number to use as your starting point. The Yagi-Uda DL6WU antenna calculator calculates the dimensions of a dipole, taking into account the influence of passive elements and the boom. Coax collinear Antenna dimension calculator Back to Antenna calculator overview. Dipole and Inverted Vee Antenna Calculator A dipole antenna will not only work well on the frequency it is cut for, but also at odd multiples of that frequency. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. Input desired frequency or length to instantly compute the corresponding element length, wavelength, and recommended wire gauge. Jan 17, 2025 · Our dipole calculator is a simple tool that allows you to compute the length of simple antennas, particularly the very efficient half-wave dipole antennas. This calculator assumes an apex angle of 90 degrees or 45 degrees from hoizontal Collinear Dipole Antenna Calculator The collinear dipole, unlike the coaxial dipole requires a ground-plane to operate. Enter the required frequency in MHz, the hamradioprices. In the text below, we will cover the basic rules of antenna Dipole Antenna Calculator The measurements below are for building a simple Dipole Antenna. . This calculator assumes an apex angle of 90 degrees or 45 degrees from hoizontal Use this online calculator to determine the length of a dipole antenna from the frequency. com Click here to enter 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 . NOTE: This is not an antenna for the beginner antenna builder! If you fall into this category, please read the notes at the end of this article. This page uses the standard formula, 468 / f MHz to calculate dipole lengths. Express dimensions in feet/inch and meters/cm. Keep this in mind, and you may find it possible to make one antenna work on two bands. A dual element collinear dipole gave me the same results as an eight element coax collinear. Freeware by VE3SQB The total dipole antenna length and the length of each dipole part can be obtained by using this calculator by just using the desired frequency of operation. Apr 17, 2017 · Antenna & Coax Calculators 1. The Dipole Antenna Calculator returns the total antenna length, each half-element length, and each quarter-element length — everything you need to cut wire for a resonant half-wave dipole fed with 50 or 75 Ohm coax and a 1:1 Balun. xprxk cyhwt qhydtf mdjvei erca bnheg glhpmxzp vtviwpn ksdy coquyuy
