Or, put a good dummy load at the far end, and measure the RF power out of the
exciter into the cable. Now, without changing RF level, move the power meter
to the dummy load end and measure the power being delivered to the dummy load.
Now you've measured the actual loss in the cable. Compare it with the
manufacturer's specified value, and you know if it has degraded. If the
is something you want to live with, keep using the cable!
Remember, the loss of brand-new, high-quality cable IS NOT zero!
