[TowerTalk] Sealing Ends of Phillystran HPTG-1200

[Marsh Stewart]

I used a dab of liquid electrical tape to seal the ends of the Phillystran
HPTG-1200 on my new DXU-32. The Phillystran "soaked up" some of the first
application so I put on a second coat on each end. 

But then I had a KLM-34XA that used Phillystran for the truss cable up for
over 20 years. I never did anything to the ends of the Phillystran. The
Phillystran never broke or stretched. And we get lots of rain where I live.

Subject: [TowerTalk] Sealing Ends of Phillystran HPTG-1200

I just finished assembling my M2 40M4LLDD 40 meter Yagi.  The element
supports use Phillystran HPTG-1200.. I've heard that the inner fiber core
of Phillystran is highly affected by water intrusion, but the manual makes
no mention of sealing or capping the ends of the Phillystran.

Do I need to seal or cap the ends to protect against water intrusion?  If
so, what is the preferred way to do this?

Thank you,
