    Anybody happen to have the details of the dipper coils for the MFJ-259B Antenna
    Analyzer? Mine have become lost in a garage/workshop cleanout that went awry.

    Need number of turns, coil diameter, coil length if possible. Think I can
    remember the rest of the details well enough to rebuild them.

    Thanks for your help

    Yep!!! My MFJ-259B has lots of guts too.
    The dipper coils are used to make the Analyzer operate like a grid dip meter.
    Extremely useful for tuning traps, tanks, etc. They are an accessory to the
    Analyzer; I think the part number for them is MFJ-66.
    There are two coils in the set, one for 1.8 MHz to 50 MHz, the other covers 20
    MHz to 170 MHz.

    Cheers!

    Wow! I learned something today. Even old farts can learn something new.

    BTW: my grid dipper is a real grid dipper ... AN/PRM-10. Anybody remember that
    old boatanchor?

    =======================
    Assuming that these dipper coils are connected to a PL259 plug for
    connecting to the MFJ259B 's SO239 socket , it should not be too
    difficult to homebrew the coils .........I'll have a go at that.

    Yeppers!!! I surely do remember the PRM-10. Almost bought one at a hamfest a
    few years ago, but it looked like it had been through just about every battle in
    WWII, Vietnam and Desert Storm.

    They were good instruments; I used them while I was in the Navy as an ET during
    the 60s. I found them to be quite useful while overhauling old comm equipment
    while I was aboard the USS Vulcan (AR-5) during that period. Got a tremendous
    amount of experience on that ship.

    Cheers!!!!
