[TowerTalk] Sealing Ends of Phillystran HPTG-1200

[Roger (K8RI) on TT]

They are inexpensive caps about an inch long apparently of the same 
material as the Phillystran jacket.  I give then a shot of Silastic RTV 
(TM0and install with a twisting motion that leaves a small ridge at the 
end of the cap.  I advise waiting for the material to cure before 
installing the Phillystran, although rain will speed the cure. Just keep 
it out of the Phillystran.  I've had some up over 10 years and they are 
like new
