The rubber duck antenna that comes with the pj2 gives decent range and clarity. I live 4nm from an airport and can pickup the atis and yes some tower or aircraft flying overhead. It the car its obviously pretty bad, so I put this on top and it improves clarify and I want to say range as well. At least on the receiving side. Couldnt say about transmitting quality.
