[Elecraft] OT: Frequency probe

[Greg Derda]

I've searched and Googled all over for this, but can find nothing.  I 
have both a benchtop frequency counter (from a Hamfest w/ no probe), 
and the NorCal FCC-1, and I need a frequency probe for both of them.  I 
have some RG-174 and BNC connectors.

For the benchtop counter, I presume I connect the center conductor and 
shield to the BNC connector in the usual way.

For the FCC-1, there are two holes on the board for the conductor and 
ground.

Question is, what do I do on the other end?  Do I need a capacitor like 
the K2's internal probe has?  Do I need to ground the shield to the 
circuit under test (with a clip)?  Is there more than one kind of probe 
depending on the type of measurement?

One goal of mine is to use the FCC-1 with the AMQRP Tenna Dipper (which 
has one hole for frequency measurement).  So, in addition to learning 
how to build a generic probe, I am also hoping to learn enough (from 
you all) to let me know whether I need to ground the shield to the 
Tenna Dipper, in addition to connecting the center conductor to that 
hole.

Any and all comments will be greatly appreciated!

Thank you & 73,
Greg
