Hi,

I live in a 44 year old apartment building in Manhattan. I'm currently
doing renovations and I've removed an old, dented, paint-encrusted TV
antenna wall jack from the living room. I'd like to replace it with
its modern equivalent so I can use the building's roof antenna for
HDTV and FM radio reception.

I don't know exactly what this thing is or how to replace it properly.
Ideally I'd like to have a standard 75 ohm coax output. Any help would
be appreciated. Here's a description of the old jack:

The jack accepts 2 coax cable inputs at the back. and provides 2 screw
terminal outputs on the front. The screw terminals on the front are
presumably for the old standard 300 ohm TV wiring. Here's a
schematic:
