If that were true then the BIG boys on 160m would have no need for
tall vertical transmitting antennas and traveling wave (Beverage)
receive antennas. They could just use one or the other for both
transmitting and receiving, but they don't. That's because one is
better for transmitting and one is better for receiving.
