I have been looking at a lot of coax specs and talking to a lot of people
about it. From what I see two stand out in the "flexible" area Westflex 103
and Buryflex 9914. Straight runs benefit from LM-400 or LM-600.
The best advice I have received for a very helpful gent is from Steve Davis
at Davis RF http://www.davisrf.com.
I have another question to add.
What is the minimum static bending radius on coax. Very few give that
detail. And how do you deal with an installation of say LM-600 that has to
go horizontally then vertically (from the 12th floor apartment to the roof @
15th floor)? Is it OK to fit a 90 degree connector? What sort of loss would
there be? I have hear mention of 1.5db per connector?
