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.

Thanks for your help

MFJ makes plug-in external coils for the MFJ-259 that converts the
analyzer into a grid dip meter. They attach to the bnc connector.

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!

I'm sorry I can't be more helpful, but someone pointed me to a German
version of the Manual that a ham wrote for it. I have forgotten the URL. :-(

It includes instructions that even a non German reader can understand
for making a set of coils that far outperform the MFJ ones. They
can be made for a few dollars assuming you have a source for small
white PVC pipe, BNC connectors and enameled magnet wire, none of which
I can get locally. :-(

Geoff.

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!!!!
