Default Homemade coils for using an MFJ analyzer as a dip meter?

Geoff and all:
The 'dip' function is simply a 2- or 3-to-1 series-connected mismatch with a
capacitor, resistor, and coil to couple to the device-under-test. The dut
makes the meter wiggle by absorbing a bit of power, for a visible indication
of 'resonance'. That's all, afaik.

I have an MFJ modle 249 (the original with a meter) antenna analyzer. MFJ
sells a kit of two coils to make it into a dip meter.

I would like to use it to measure the resonant fequency of a traps I
am building, but am unable to purchase the coils.

Is there a way to make then on your own?

TIA,

Geoff.
