OB2-40

2 element Yagi 40m

=>  

High efficient 2 element monobander for the 40m band:   
       

->  

The OptiBeam high Q air coil reduces the length of the elements nearly lossfree down to a little bit below convenient 15 meters
  ->   Due to the especially developed „40m decoupling stubs“ interaction is avoided to other Yagis in the frequency range of 14 to 30 MHZ
