Electromagnetic Compatibility (EMC) consulting and training. Laquo; Ferrite Cores For Low-Frequency EMI Cable Suppression. EMC Training in the Steel City. Antenna Modeling Software for the MAC. Which costs about $100. I have always wished to have a similar program for the MAC. I have now found an even better program than EZNEC, that is written specifically for the MAC. The program is “cocoaNEC” ( http:/ www.w7ay.net/site/Applications/cocoaNEC/. The antenna characteristics can be input in either one of tw...

Understanding, designing, constructing and using radio antennas. 22 Nov 08 Antennablog is back! Has it really been a year since I last posted here? You may have noticed that the domain has changed – from antennablog.com to antennablog.net. Due to the bungling of a domain name registrar I lost the earlier name, which someone grabbed and has had it parked ever since hoping I might be willing to buy it back. Fat chance! I have had to settle for this one. Rebuilding the blog with a new version of WordPress.

The W8IO Antenna Site -. Updated 24 July 2016). In 1984, partly to meet the demand for MININEC as well as share other computer algorithms, the authors teamed up with two colleagues, Peter Li and Dan Tam. They published a book that contained an improved version of MININEC along with some other useful algorithms. MININEC2, as it became known, was not significantly different from its predecessor, but the limitation for wires intersecting the ground plane was removed. Close-spaced wires of different diameters.
