You've probably seen
cable-TV installations where the bare coaxial cable simply enters a
room via a crude hole drilled through the floor or a baseboard (maybe
you've seen them in your own house!). They're functional but not too
decorative. For a more finished and permanent installation, do the job
right and install a bona-fide wall jack.
||Make a cutout opening 1 1/2 inches wide and 3 3/4 inches high at the television-jack location. Pull the cable through the opening, and install two television-jack mounting brackets in the cutout|
||Use an adjustable wrench to attach the cable F-connector to the back of the television jack. Then attach the jack to the wall by screwing it onto the mounting brackets.|
