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
What coils?
My MFJ-259B has all the guts inside!!!

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!!!!
