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'

If you need a quiet, easy-to-make HF antenna, then this delta loop project from Callum McCormick (M0MCX) may be what you need. The delta loop antenna can be configured to favor horizontal or vertical polarization.  If you feed the antenna with twin lead into a balanced antenna "tuner", you will get multi-band HF capability. Here are a few comments from Callum: Lots of myth about vertically polarised delta loop antennas - lets take the covers off and have a look. Callum. DX Commander.

If you want to add a bit more "punch" to your 2 meter signal, then this antenna project from Australian radio amateur Peter Parker (VK3YE) is what you need. Peter says this vertical extended double zepp antenna is ideal for VHF FM simplex and repeater applications. Here are a few comments from Peter: A very simple but very good omnidirectional vertical antenna for VHF FM simplex and repeaters. But that's not all. What is it? It's a extended double zepp antenna for 2m. And it does 6m as well. Watch to find out how easy one is to build.

Thanks to Tim (G5TM) for this simple HF antenna project.  Tim's antenna is a modified doublet, with a total length of 33 feet (10.06 meters).  The antenna covers 20 through 10 meters. Here's some general comments from Tim: A simple but effective multiband HF antenna for small spaces. Covering 20 through 10 metres and offering good gain for the higher HF bands. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

The weekend is a perfect time to spend on ham radio.  In this video, Carl (M0SZT) uses his free time to build a simple, effective 17 meter antenna for some "at home" operating. If you have no prior commitments for the weekend, spend some time improving your ham shack or designing a new antenna project. Here are some general comments from Carl: I had the house mostly to myself for a weekend which means I can play a bit more ham radio than normal. I made a number of European contacts on FT8 which were easy, I managed Japan and Russia on FT8, with a small number of voice contacts. I was happy with this. The coax is Formula Zero F Zero Ultra Low Loss Coax I'm a licensed amateur radio operator from the United Kingdom. My YouTube channel features videos focusing on oper
