Have you ever wondered what these four things have in common? No, ofĬourse not, me neither! But perhaps you have wondered why a SmithĬhart has such strange grid lines. Speedometers, Thermometers, SWR Meters, and Smith Charts He asked me to write this small program incorporating his work and I was happy to oblige. Cebik, W4RNL, developed an algorithm for calculating the dimensions of a Moxon Rectangle antenna.

Neither will mute annoying TV commercials. Two workbooks that provide a remote control link between Zplots and the W5BIG AIM device or the DG8SAQ VNWA device, respectively. Nothing to do with Albert Einstein, really.įeed2EL - Feed Systems for a Two-Element Phased ArrayĪn Excel workbook to aid in the design of a feed system for a typical two-element phased array. Two small workbooks showing various formulas that are used when dealing with transmission lines. Online coax loss calculators that use SWR as one of the inputs certainly are convenient but can you trust the results? Alternative tools which are much more accurate are readily available. EZNEC Patterns: (click on picture for larger view) 20m Elevation Pattern.

It can also be used for other member download files but I will have to put the files up for you file found. This page will list files used or requested during our repeater EZNEC meetings. TechTalk is streamed live on Echolink via KN4ODS/R in Griffin GA. "Additional Loss Due to SWR" is in Quotes for a Reason Below you will find the EZNEC Patterns, the SWR values (theorical and real) and at the bottom of the page, the EZNEC files to download so you can experiement by yourself. TechTalk is Sunday and Monday nights at 9PM EDST. XLGTa - Antenna Gain/Temperature and Other 3D MetricsĪn Excel (XL) workbook to calculate antenna gain/temperature ratio (G/Ta), average gain, directivity, and other metrics by using 3D pattern data from EZNEC, AutoEZ, 4nec2, A.M., or MMANA-GAL.

  • 4NEC2 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler.AutoEZ works in conjunction with the EZNEC antenna modeling program and allows you to use variables to control diverse aspects of the model.
  • NEC2 is a 'Method of Moments' simulation program developed under contract from the US Navy in the early 1980's which is now in the public domain, and runs on just about any modern computer.
  • The first step down the path of antenna design I took was to get to know the NEC2 program (or since it's FORTRAN, 'codes'), and the free Windows GUI, 4NEC2.
