This is post 2681 in a continuing series of simple ham radio antennas.

If you want a multiband HF antenna with only one antenna design, please consider the "Linked Dipole Antenna."

In this video from "Red Summit RF", we learn how to design, build, test, and use this easily-made antenna.

Here are some general comments about the project:

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.

It's worth the extra cost to me.
