Hello all,

I am wondering if anyone knows how to use a grid dip meter to measure coax electrical length.   Must I use a shorted half wave lenght and trim, or can I use an open quarter wave and trim?  How can I couple it to the grid dip meter?  I obviously set the meter at the desired frequency, but do I use the meters coil assembly or plug the coax directly into the meter?

Thanks in advance,
