Balanced Line Balun - RG302
This choke balun is similar to our wide-band model, but it designed
to connect the output of an unbalanced antenna tuner with SO239
plug to a symmetric balanced line. We use 75 Ohm RG302 teflon
coax for this coax to reduce the looses when a higher impedance
is matched. As high voltage can occur at the banana plugs, the
choke should be only used up to 100 watt output.
