    If there are no part numbers, maybe you could post a picture?

    Most GPS antennas have some sort of an LNA (Low Noise Amplifier) built in, which is fed power up the coax from the GPS receiver. These are usually referred to as active antennas.
    The only trick is that different antennas have different voltage requirements, and you need to be sure that the new antenna is the same voltage as the old one
