In this video, we will be building a QRPGuys End-Fed Half Wave (EFHW) antenna for 40m portable operations, specifically for Parks on the Air (POTA) and Summits on the Air (SOTA). This antenna is compact, lightweight, and easy to deploy, making it perfect for use in the field.
We will start by showing you the materials and tools you will need to build this antenna. We will then walk you through the steps of building the antenna, including how to measure and cut the wire, and how to attach the QRPGuys matching unit.
Once the antenna is built, we will show you how to deploy it in the field. We will also touch on tuning the antenna using a NanoVNA antenna analyzer and how to adjust the length of the wire to optimize its performance (spoiler alert: no adjustments needed this time)!
