Re: Stus-List Test new VHF wire for dummies...
Dave, Thank you so much. That was just what I needed. Thanks for the advice. Hope to do the same for you some day. Sent from my Android. Please forgive typos. Thank you.

I doubt I meet your requirement however a basic test: Use a digital ohmmeter to test for open, (none or poor conductivity) short (no resistance between shield and centre conductor). You will need a meter, and a short jumper wire with alligator clips each end. Use the resistance scale (ohms). To test, measure resistance between the pin and housing. Should be infinite (meaning they are not accidentally connected to each other). If there is conductivity, one of the terminations has allowed the shield to contact the conductor. You will need to redo. If ok, then use the jumper cable to connect the pin to the housing at one end and measure again at the other. This time there should be conductivity with some resistance (cumulative effect of a long run of cable, out and back) If the jumper test shows infinite resistance, then you have either jumpered poorly or one of the connections isn’t. Redo. Wiggle and yank each connection then test again. Dave.
