A 40m High Performance Antenna for Field Day

The Nashua Area Radio Society has been using a 3-element 40m wire beam antenna for Field Day for the last several years. The antenna uses three guyed 50 ft. fiberglass masts from Max-Gain Systems. The antenna uses three inverted-V style elements separated by a little over 50 ft. Since we are in the northeastern United States, we can point the antenna on a fixed, 260° heading and it covers the entire U.S. well.

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.

Breadboarding Software

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.

Breadboard Software

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 Software

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

Breadboard Software

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

Get ready for Antenna Modeling

Antenna Modeling
EZNEC Example

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.

Please download the antenna modeling software for your platform,  and download the slides for this presentation from the Tech Night web page. The slides have a lot of detail on them, and it will be much easier to see the subtleties on your own screen.

So, bring your laptop with software and slides, and we’ll have you modeling antennas by the end of the evening. See you there!

Scott, NE1RD
