I'll take one apart if nobody else responds. I have both the "ham band"
28-66-02 duplexers (100 dB isolation, 0.6 dB loss, 5 MHz split) and also the
same thing in 450-470 MHz (28-70-02) - I don't think the loops are different
between the two, just harness cable lengths. I think I also have a
28-70-09, which has slightly different loops which yield higher loss (1.2
dB) but deeper notches and more mid-band rejection.
