Transponder uplink frequency is 1030 MHz, downlink frequency is 1090 MHz.

So wouldn't we be building a transponder dipole with each leg about

2.75 inches (or so) long? The 6.25 inch per leg dimension would fit

an operating frequency close to 450 MHz.

    Good catch!  I put the dyslexic brain onto the

    6.25 and read it as 2.65 . . . and indeed, the

    original figure may have been a typo. But yes

    indeed, an antenna 12.5" long would make a poor

    transponder antenna.
