The W5UN Quagi 97 is a computer optimized quagi derived from the original W5UN Quagi of the early 1980s. The length of the 1997 model has been deliberately shortened to allow it fit on a 24 foot boom. Performance is substantially higher than that of the original antenna. It now compares favorably with yagis of…

The RockLoop Antenna
W9SCH described this small loop in Sprat 60 and it has proved useful to the QRPer, especially where space is at a premium. It is basically a variant of the usual magnetic loop, using a toroid balun to get a reasonable match on the three bands. A slow motion drive would prove useful on the…
CobWebb 5 band antenna
I have a very small back garden and am limited with what type of antenna I can use. I built my first antenna in July 2004. If you are looking at this after speaking to me, you know it works. It is basically a 5 band antenna comprising of 5 full half wave dipoles for…
The ever-popular inverted L antenna
Ever wanted to install a shortwave receiving antenna FAST?!!! Then I am almost sure that you will want to learn more about the “Inverted L” antenna… About the easiest effective skywire to build … Just two supports… may be two masts, a mast and a tree, a mast and a nearby building… it need not…
A Novice Multiband Vertical Antenna
Putting your first ham radio station together can be an expensive proposition. One way to cut costs is to keep the antenna simple. Here’s how WB1FSB shaved the price and provided four band operation. https://drive.google.com/file/d/1os8GDj9Ydcp93W6r9TxBPJXp7zqPJOGu/preview
Homebrew G5RV All Bander
The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands are covered, including 30, 17, and 12. The G5RV has high SWR, by design, on most bands and a tuner is required. Unlike most dipoles, the “basic” design is not a 1/2 wave, but instead a 3/2 wave dipole on 20 meters. A…
55′ Vertical Antenna For 40/80/160 Meters
The basic antenna is a vertical monopole, using elevated radials to complete the “ground plane.” I use it only on the weekends, primarily for contests, thus it is designed to be raised and lowered with a minimum of fuss. It is a full-size 40 meter 1/4 wavelength vertical, with from four to eight tuned radials…
A Stealthy 75 meter Antenna
The 75 meter dipole at K7ZB was put up to meet the need for making contacts with friends in the Southwest and Southern California. As usual, it had to be put up so no one can see it from the surrounding neighborhood. The objective was accomplished as shown below, which is the site drawing for…

20/40 Dual Band Dipole
This is a simple dipole built for two-band operation that I made for portable use with my 20 and 40 meter QRP rigs. It was built to take along camping so I would only have to take & put up one antenna instead of two. The antenna consists of a regular 40 meter dipole using a…
