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.
40m V-Beam – EZNEC Antenna View
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.
