Correct, I was referring to the shorter more tuned antenna. Early units came with identical antennas for PCAS and Flarm (except the connector). If your antennas are identical in size and you have reception issues you may want to consider replacing with the newer one. My newer antenna also came with shorter coax. It is also possible that my antenna had a defect, but once I replaced the antenna the results were remarkably better.
