[QUOTE="Lazarus, post: 636443, member: 323322"] Well if it is new, l should remove and refit the F connectors first as it is far more likely (but not certain) that the problem lies there. Did you install the cable yourself, or was it done on your behalf? If the F connections are proved sound, leaving the hidden cabling the sole remaining suspect, then if it was damaged during installation it might be best to refer the matter back to the Installer (If it wasn't you!). To be honest, it perhaps should have been checked for continuity and insulation resistance at the time. To check continuity, go to one end and short circuit the inner core and sheath. Connect a multimeter across the core and braid at the other end. Similarly, a simple insulation resistance check can also be carried out by leaving the multimeter connected and parting the core and sheath at the other end - obviously this isn't a true insulation resistance check, but it will tell you if the core and sheath are short circuited inadvertently somewhere along the cable run.
