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

May 2016... Very many thanks to all of you who supported me by building and using my designs! You've arrived at the index page to my websites, buttons 1. & 2. below to the projects. Recent page updates: TANT, Balun or not?, Software, and Q-factor & Stability. There are three types of yagi, those with resonance LF of the band being the most common. It is unusual to see true resonance in-band or HF of the band, both of these offer the greatest stability!

Early 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!

EME enthusiasts and DXers take note that my preference is for the UR5EAZ yagi comparison table which exposes myths concerning claims that certain yagi types can receive weaker signals. Vladimir has taken seriously those comments by Owen Duffy, and so looks at system performance. This includes your receiver NF (dB) and bandwidth (Hz) thus revealing the minimum detected signal (dBm) capability. My website hosts both XHTML (static version) and interactive table (.xls). In my opinion this is a big step forward in the right direction!...

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.
