I know most people reading the thread are probably aware of this, but just in case anyone isn't.....
When it comes to clipping center and shield together to trace a cable with an ohmmeter or other simple continuity tester, remember that cables which run to an antenna may show a DC short under normal conditions anyway. A folded dipole on a regular Yagi array, for example, will do so. It might look like a dead short to DC, but it isn't at RF!
And a little off-topic I know, but when it comes to simple DC continuity tests, I wonder how many other U.K. readers still have one of the old dark green Hosiden Besson "Bleeptest" units, as were standard GPO issue for many years?
