[TenTec] Trading radios

[Mike Schatzberg]

In my case the RF is radiated from my Yagi and the coax shield picks up the radiation between the antenna feed point and the radio. 

With good quality cable, the center conductor is not radiating.  However, the shield may indeed be carrying current. 

Stations with RFI often only experience interference with their directional arrays with the antenna in a certain alignment with their cable. 

I use a 1:1 current balun at my Yagi hairpin feed point, and the line isolator at the input to my amplifier,  between it and the Orion II. 

Seems to work well with all the radios here. 

73,
