Topband: Verifying integrity of 75 ohm coax.

[Greg - ZL3IX]

Hi Gary,

if you have not made up the Time Domain Reflectometer in the ARRL 
Antenna Book, then now is a good time to do so.  Disconnect the coax at 
the far and and terminate it 75, and then apply the TDR test. You will 
see not only whether the coax is OK, but if not OK, where the 
discontinuity is.

There is a bit of an investment to make now, as making up the TDR may 
not be the quickest way to solve your immediate problem, but it will 
certainly save you time in the event of future occurrences.

73, Greg, ZL3IX
