Our 40m V-Beam antenna was initially designed using EZNEC 5.0. It was manually optimized for decent gain and front to back performance and it worked quite well. Recently, we decided to try automatic optimization software on the antenna as part of a tune-up on the design for Field Day 2018. After looking around on the Internet a bit, we discovered a software package called AutoEZ which looked ideal the my project. You can read more about the optimization project and see the results via the link below.
Our Field Day Wire Antenna information package has been updated to reflect the results of the optimization work. We have also added additional information to make the setup and tuning of our wire antenna including the 40m V-Beam easier. You can see the information package here.
Here is some best free virtual breadboard software to design electronic circuits. You can design a sequential or logical circuit on a breadboard and then simulate that too. Just drag and drop the circuit components on the board.
FRITZING offers a long list of electronic and electrical devices that you can add to the breadboard. Export the design as PDF, JPG, PNG and other formats. Free but donation suggested. FRITZING
BREADBOARD SIMULATOR is free and quite powerful. It not only lets you design a circuit on breadboard but you can even simulate it. The software is portable so it can be used from a USB drive easily. Design, hit the PLAY button and if it is correct, save the project but you can only save the project in the software itself. Breadboard Simulator
IC on Bread is free and open source. It is a simple software for newbie students to design a basic IC circuit and simulate that. It can be exported as an image. You can make wire connections and add different LEDs at different positions. After design switch on the power supply and see the flow of the current and analyze it. IC on Bread
The March Tech Night (March 13, 2018) will have an introduction to antenna modeling by me, Scott, NE1RD. I’ll begin by going through some antenna theory and then proceed on to the NEC-2 software and its popular front ends EZNEC and CocoaNEC. (Both the evaluation/demo version of EZNEC, and the Macintosh-based CocoaNEC are free.) LINUX users should consider getting Andy (KB1OIQ) Stewart’s Andy’s Ham Radio Linux suite. The main concepts you’ll learn will apply equally well to any of these programs.
