11 Inspect and ensure that the copper center conductor only protrudes 1/8 inch (3.2 mm)
nominally beyond the rim of the F-connector. Trim if necessary.
The center conductor length must be a minimum of 1/16 inch (1.6 mm)
to a maximum of 1/8 inch (3.2 mm) protrusion beyond the rim of the F
type connector. It must be straight and cylindrical without any burrs at
the end. Failure to follow this technique could result in damage to the
satellite router, BUC, LNB connector and/or possible intermittent
service.
