[TowerTalk] Shrink Tubing

[Roger (K8RI) on TT]

As Jim does, so do I. 
http://www.rogerhalstead.com/ham_files/connectors.htm  shows using the 
flooded (adhesive lined - hot melt glue) heavy wall on LMR400.  The big 
stuff will shrink to 0.22", but using the 2-step method gives a much 
sturdier connection and make in-line UHF splices reasonably strong.
