Which should be more efficient: Using an ATR-30 to match a 300 ohm load
directly through a W2DU type balun, or using the same tuner to match 150
ohms using a CWS Bytemark 2:1 balun? Bandwidth is not a concern.I already
have the tuner and baluns. I realize there may be little difference between
the two choices, but I will be using the tuner and one of the baluns
anyway.
