Heliax acting strangely: Help?

<I still have a one foot length we removed, hanging on the workshop wall. It's there as a reminder that even professionally and correctly installed outside devices can be the source of trouble over time - and to follow a logical troubleshooting path at all times.  I'm sure a TDR would have got us there faster...

##  I suspect if a wattmeter was temp inserted at top of tower, you would have been in for a rude awakening.   A   buddy had water in his LDF-4  heliax.   It had gotten in at the top of the rotating tower, where it was  spliced into another piece of
heliax going out along the boom. And both were the flexible version of .5 inch heliax.   He  had previously removed the connector at the bottom of the tower, where it was plugged into the hb remote switch box..and out came a bit  of water.
That entire length was ruined.  Water had gotten in the top, and eventually migrated down the entire length.   Connectors at each end were  7-16 Dins.    I have heard a few water ingress stories here in the past..on tower talk.... with folks using the flexible version of  .5 inch heliax.
