Of course what you said is true, but it is still better to have a matched
antenna on receive. There is always the possiblity of very low atmosheric
noise on a given night and the extra signal just might make the difference,
especially on 10 meters. Why do people insist on using a 9 to 1 balun on
receive only beverage antennas?
