Logical progression from Speedometers to Smith charts that will makeĬoncerned or confused about downloading an Excel workbook that may contain a virus?
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. "Additional Loss Due to SWR" is in Quotes for a Reason 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. Watch impedance points change on a Smith chart as you quickly vary input parameters using spin buttons. TLDetails - Transmission Line Program with Animated ChartsĮxperiment with transmission lines. Zplots uses Excel's charting capabilities to plot impedance data obtained from a variety of sources, including the W5BIG AIM4170 Antenna Analyzer, the N2PK Vector Network Analyzer, and several different antenna modeling programs.

7.0 such as virtual wires, realistic transmission lines with loss, transformers, L networks (which can be combined to form T and Pi networks), and parallel connected loads.

AutoEZ can take full advantage of all the features in EZNEC v. You can then run multiple EZNEC test cases while AutoEZ automatically changes one or more variables between runs. AutoEZ works in conjunction with the EZNEC antenna modeling program and allows you to use variables to control diverse aspects of the model.
