Four over Four for 144MHz
- This article describes the 144MHz horizontally polarised antenna at VK1OD in November 2008.
The antenna uses two identical four element arrays that were constructed around 1970
Dual band 6m/4m Yagi
- This antenna was optimized with the goal to minimize any changes in 6jxx6 impedance/lobes. The result is a 7 el on 70 MHz with a little loss of gain comparing with the other monobands of the same lenght.
