Bill,
Often low efficiency antennas make great low noise receiving antennas -
example is a multiturn loop which can be quite directional, but transmit
efficincy would be almost 'zip'. Another example is traveling wave antennas
such as the Beverage - which also are directional, but the efficiency is low
and therefore unsuitable for transmitting.
By using the K2 Rant, one can automatically select the Rx antenna on any
band separate from the selection of the transmitting antenna.
This is often used with great success on 160 (and 80 meters) where a low
noise directional antenna is used for receiving and a vertical is used for
transmitting.
