The difference between "satisfactory" in receiving and in transmitting antennas
is that in receiving, one just needs an antenna that provides signals strong
enough over the on-frequency noise for the receiver to process.

In transmitting, the output has to be a strong as possible to be above the
noise in the desired receiving location. A better antenna will increase the
transmission's erp toward the desired direction.

In summary:
For better reception, put your money into the receiver.
For better transmission, put your money into the antenna.
