TROUBLESHOOTING WITH THE MFJ-259B ANTENNA ANALYZERWhile trying to work some HF DX, I noticed my RF output had dropped to zero and the SWR had gone sky high. The only thing between the input and output connectors is the TR relay.Phillip Mikula...

As the load on the ANTENNA connector approaches 50 ohms resistive, the meter reads a lower amount (toward 1:1). By connecting a small coil through the adapter to the ANTENNA connector, an SWR Analyzer can be used to test external circuits for resonance. The magnetic field surrounding the ...
The MFJ-259C antenna analyzer has been very useful to me as a new ham. In the March 2017 "Product Review"column, Phil Salas, AD5X, wrote about the excessive sensitivity of the tuning knob on MFJ analyzers (particularly regarding the 269C, but the front configuration of the 259C seems ...
