I am fully aware of the virtues, and expense, of a TDR. For this audience who are not degreed engineers and just want the Telly in the camper to work, the method given for finding shorts and opens (bad cables) and the associated $5 cost and minimal training will work fine.
Impedance is not measured here. Only DC resistance. One person working alone, one measurement. That's all. The test equipment you speak off can cost more than a camper.
Geeesh.
Exactly! Geeesh indeed! Simple and easy. I had to do that to sort out which of three pieces of coax was which at the other end of the rig. I shorted one, dummy load (a 100 Watt one but who cares) on the second and the third line open. It would have been even easier but one was shorted! Had to move the dummy load once.
