G4CQM's Amateur (Ham) Radio VHF/UHF Yagi Antenna Projects

23 Aug 2016... Many thanks to all of you who supported me by building and using my 50-Ohm direct feed yagi designs! You've arrived at the index page to my websites, buttons 1. & 2. below to the projects...

Why are my yagis so special? - Average Q-factor is low delivering a measured degree of stability in all weather. I use a range of Software to ensure accuracy, including K6STI's unique AO Professional. Many of my designs have the cleanest patterns as seen in TANT. There is no need for a Balun either, making DE construction very easy indeed!

Some of you have asked me about a Dual Band 6/4M (50/70MHz) single feed yagi design, the CQM6N455 article spills the beans on such designs!

In 2013 I handed over to Richard Mason G6HKS and also Roger Banks GW4WND of the DXShop ownership and production of PowAbeam Antennas. Please remember it's Richard for kits & parts and Roger for ready made yagis!

Peter G3MLO has just completed building this stunning 4 x WAXXX10S AOWA yagi array. First reports of hearing the Angus beacon confirm superior performance under flat band conditions...Excellent build by Daryl VK4ADM with his own implementation of the now popular CQM12UX FLOWA. His booming signal reported several hundred kilometers distant...

An important lesson from VK4MJF: When using Stauff type clamps on 144MHz use additional spacing, raising elements sufficiently high above the boom to avoid the need for correction. Thus ensuring that your yagi is tuned correctly...An important lesson from VK4MJF: When using Stauff type clamps on 432MHz use additional spacing, raising elements sufficiently high above the boom to avoid the need for correction.
