Dear TowerTalkians,
Thanks to N4ZR and W0OPW for the following replies. I was operating from
memory; so much for my memory!
"IF ALL ELSE FAILS, READ THE INSTRUCTIONS!"

>It's called resonance <g>. This same technique is used with the RF-1 to
set the length of 1/4 and 1/2 wave stubs. The line is transforming the
infinite (open) or zero (shorted) impedance to a different one at your end
of the line. To test the quality of a line, you really need to switch to Z
and tune for lowest, then use the formula in the manual to calculate loss
and see if the cable meets spec.

> Why didn't you use the method that Autek reccomends, ie, monitoring
the Z on the RF1 at the dips. That can tell the loss better than SWR.
Their formula for loss is: Loss(db)=.17*Z.

Thanks, guys!
