[TowerTalk] Shrink Tubing on Coax & PL-259?

[K7ZO (Scott Tuthill)]

I am about to make a bunch of coax assemblies for the latest antenna 
projects at NK7U. Joe and I were talking about putting shrink tubing over 
the end of the coax and up over the end of the PL-259. We have seen this 
done on some commerically produced coax. Any thoughts on this out there?

* Does it make a difference? Is it worth it?
* If so, any recommendations on what Shrink Tubing to use and suppliers of 
it?

Thanks for the advice.
