I did not receive the original message, but just went to the radiolist 
website to read it.

In any case if you haven't, you should do a full sweep on your lines. If 
you've had any water intrusion into the line the VSWR could remain very 
low, while the actual losses are very high.

A quick sweep of the line will show any of those type problems. If the 
standard return loss sweep and distance to fault look good, then you 
really want to a single port cable loss measurement around 1.2 gigs and 
see how the cable compares to specs.

If all that provides no joy, lay the path out on google earth and follow 
it to see if there is something new that you didn't know about.
