    I've spent the last four hours looking at websites for coax trying to find out what this is but have had no luck. I'm hoping someone here can easily identify it. It's all white and PTFE. It's only used on the input side of my SB-220.

    Single shield
    OD - ~.160
    Center conductor - ~.035
    Diaelectric ~ .110

    Take a look at RG-303. PTFE dielectric and very, very close to your measurements.

    The SB-220 didn't come with that, so somebody changed it either during the build or afterwards.

    It's good stuff, mostly because you can "solder" it for a very long time without fear of melting anything.:)
