In my MFJ, the toroid and calibration cap are about 1/2" apart.

The story that the length of line inside the meter is used to detect
and measure standing wave ratios is just another old-wives' tale which
confuses CB-ers, novices and professional engineers alike.

And if you will remember, the original question didn't involve the
SWR meter at all. The question was: Are my 2-foot sections of RG-400
connected to my SWR meter long enough to ensure that the SWR meter
reading is valid for the coax? Remember that argument?

The threads for the past few days have all diverged from that
original question which was:

How long must the 50 ohm coax connected to the SWR meter be
for the SWR meter to report a valid SWR *on that coax*? The
answer obviously cannot be zero length.
