2 elements YAGI for field day operation - A wire yagi antenna for 20 and 40 meters band suitable for outdoor and field day operations

7elements yagi for 70MHz - 7ele homemade DK7ZB yagi for 70MHz

Dualband yagi for 50 70 Mhz - PA5DD version of the dual band yagi antenna for 50 and 70 Mhz

EF0610 6 Meters yagi antenna - This is a plan for a 10 elements yagi antenna for 50 mhz

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.
