Here are some comments from "Red Summit RF":
I take you through my steps to build this 20 meter-30 meter-40 meter linked dipole antenna, including construction of the insulators, and a trip into the back yard to tune it up. I've built quite a number of these antennas and have strictly use them in the field for SOTA for many years. This is a great antenna to use for portable ops like Summits on the Air, Parks on the Air, or similar events. They perform quite well. The one I constructed only weighs 8 oz. It is best suited for QRP. I'm not sure how well it would perform above 20 watts. Twitter: @NJ7V_ Instagram: RedSummitRF
