AutoEZ  Automated use of EZNEC
AutoEZ works in conjunction with the EZNEC antenna modeling program and allows you to use variables to control diverse aspects of the model. You can then run multiple EZNEC test cases while AutoEZ automatically changes one or more variables between runs. AutoEZ can take full advantage of all the features in EZNEC v. 5.0 and v. 6.0 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.Looking for the SteppIR Yagi models? Click the icon or click here.
Zplots  Plot Impedance Data
TLDetails  Transmission Line Program with Animated Charts
Experiment with transmission lines. Watch impedance points change on a Smith chart as you quickly vary input parameters using spin buttons. Plot matched line loss versus frequency.
XLGTa  Antenna Gain/Temperature and Other 3D Metrics
An 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 MMANAGAL.
"Additional Loss Due to SWR" is in Quotes for a Reason
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.
Transmission Line Math
Two small workbooks showing various formulas that are used when dealing with transmission lines. Nothing to do with Albert Einstein, really.
Feed2EL  Feed Systems for a TwoElement Phased Array
An Excel workbook to aid in the design of a feed system for a typical twoelement phased array.
Remote Control for AIM and VNWA
Two workbooks that provide a remote control link between Zplots and the W5BIG AIM device or the DG8SAQ VNWA device, respectively. Neither will mute annoying TV commercials.
MoxGen  Moxon Rectangle Generator
L. B. Cebik, W4RNL, developed an algorithm for calculating the dimensions of a Moxon Rectangle antenna. He asked me to write this small program incorporating his work and I was happy to oblige.
