Alf Traeger's, VK5AX antenna is a quarter-wave employing a tuned counterpoise system. This proved to be an extremely effective antenna system, which it needed to be, considering the low transmitter power and the long distances over which the equipment was required to operate.

This is Traeger's antenna system used for the early Flying Doctor's remote stations. The centre dipole was approx tuned to the center frequeny . The network was approved for 2, 4 and 8Mhz frequencies by the then PMG's Department. He then used a separate counterpoise wire approx. seven feet above the ground tuned to suit each frequency. The max radiation was at approx 45 degrees to the counterpoise which insured as pointed towards the nearest base station.

The following drawing is a antenna design for the model SSB50HS radio.
