MFJ-259B coils
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.

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.

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

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