OK CECIL!!!

Leave it up to you to pull the rug out from under me...
If I have a transmitter that has 50 ohm out, and it is going to hook to
a 50 ohm cable (and I can't see how this coax is terminated) why would I
ever choose anything other than a 50 ohm calibrated swr meter to measure
it with?

Is that what I have seen on FS meters before (a rise in apparent
radiation from the coax shield--and yet match looks good) and the 1/2
wave coax is really now part of the antenna?

And, if the meter didn't give me the right reading, and cooked my "BEEG
LEENEAIR" could I sue the manufacturer, buy a yacht and live in the
Bahamas, drinking Peter Vella Merlot? grin

Warmest regards,
John

VSWR stands for Voltage Standing Wave Ratio. It's supposed to be the
ratio of the greatest voltage on a transmission line to the least
voltage on the same line. On the line with a 72 ohm Z0, and a 50 ohm
load, there exists a standing wave, and the ratio of maximum to
minimum is 1.44 whether you measure it with a 50 ohm bridge at the
beginning or not. If you define SWR as what a 50 ohm SWR bridge
measures, you haven't quite grasped the concept.

And Fred didn't ask what an SWR bridge would measure.
He asked: "What would the SWR be ... ?" You're right.
The SWR would be 1.44:1.
