Re: [TowerTalk] TH11DX and Belden 9913

[Mahlon Haunschild <mahlonhaunschild@cox.net>]

Belden 9913 has a 10 AWG solid coppper center conductor within an 
airspaced dielectric.  When moved frequently (such as in a rotator 
loop), the center conductor migrates away from the center of the 
dielectric, creating impedance bumps in the cable.  CQ Flexi 4XL is 
otherwise identical to 9913 but has a stranded center conductor, which 
is much more flexible.  It is not as susceptible to center conductor 
migration.
