Should flat coaxial designed for going through windows be avoided? Cable Modems and Wiring Issuesquote:
There is no way you're going to avoid an impedance bump with "flat" coax, and that will definitely introduce undesirable effects on the signal in the cable that are detrimental to TV as well as HSI signals. Not to mention that ingress and poor common-mode noise rejection are a problem with this sort of cable.
Mainly this sort of cable is very poorly shielded, and should really be used as a last resort.
Below is an example of flat coax.
