[TowerTalk] Buryflex Conector Help

[Roger (K8RI) on TT]

It's been quite a while since I installed any connectors, but it was 
after I lost the use of my left hand.  Instead of holding the cable in 
my left hand, I use one of the small vises that use a flexible rubber 
like connector to attach it to the workbench.  I attach the connector 
with a light touch and gentle twisting motion.  If any of the strands 
contacts outside the hole in the connector, it will fold back, even if 
there is sufficient room in the connector, so the ability to detect that 
light touch is quite important.  I have tinned the tip of a few cables, 
but never found it necessary to wrap the center before doing so. Again, 
it was after a light pull and twisting between the thumb and first two 
fingers. I only tinned a few, but never found it necessary.  I do not 
remember the number of the connectors, but they were silver plated with 
a Teflon insulator.  I believe I purchased them from Davis as well.

OTOH I have purchased cables and connectors from a number of suppliers.

Although I like LMR 400 and 600, I have pretty much gone to BuryFlex 
instead of LMR-400.  I still use LMR-600. Both the 400 and 600 have very 
tight non repeatable bend radius without the center conductor migration. 
Linear migration is still a problem on longer vertical runs.
