Great video as always. I Have a question using the 4state tuner with a 5-watt transceiver and deploying a 40-meter, (monoband) EFHW antenna do I need a UNUN or a 9/1?

@CWj38: Actually with a half-wave wire and a 49:1 or 64:1 transformer you won't need the tuner. If you use any other length than a half-wave then you would use a 9:1 and the tuner.
