What: 4:1 hybrid balun build
Where: At the Clubsite
When: April 27, 2024 9am-12pm
This antenna is quite versatile, capable of handling 100 watts and working on frequencies ranging from 80-10m. It can be used for a delta loop or an off-center fed antenna. This is my go to antenna for portable operations. It has not been tested in wet weather so keep that in mind if you’re planning a permanent install. The cost for participating in this build is $40, which covers everything except the antenna wire. The build process is expected to take around 3-4 hours. To join, please RSVP by Thursday April 18th to bmercer@eutonian.com and payment will be required upfront. Cash is preferred but we can also arrange paypal once you email me.
A small assortment of tools will help the build go smoothly. If you can bring side cutters, and a soldering iron, you can get through most of the build. I’ll bring some small tools that I have to share, but they will be limited. If you are familiar with winding torroids, that is the bulk of this build. We will also be soldering on some small connectors, and bolting the mounting studs in. I will also have a nanovna and dummy loads so we can run a sweep on each build to verify that it is constructed correctly.
The plan for the build is for everyone to have their own instruction manual that will walk you through step by step with pictures. This way everyone will have a visual to follow along with at their own pace. The instructions will also include some basic information on how to test the balun to make sure it’s functioning correctly. Having built several of these, I’ve also come up with a few helpful hints I will include along the way.
Because of the lead time in preparing the kits, I will need to know absolutely no later than April 18th if you are interested in participating.
