Probably a DC blocking capacitor. If so, it's there to prevent DC from
damaging the tuner. I once had a very expensive and bad experience when a
DC blocking capacitor was absent; they can be very important.

.......NO, not a DC blocking capacitor, although that is what a capacitor can
do, BUT it is rather a SAFETY component that isolates the television's "hot
chassis" circuitry from external metal parts and external connections such
as the antenna connector.
FIRST.... UNPLUG the television IMMEDIATELY and either replace the entire
"isolation block" (the small metal box that you described) that would
include a new antenna connector and a plug at the other end that plugs into
the tuner.... or replace the capacitor with the exact original equipment
value and rating. Again, this is a electrical shock hazard SAFETY item,
not just a tuner protection component. An omitted or wrong type of
capacitor can present a lethal and dangerous electrical shock hazard and a
fire hazard..... repair this correctly with the proper replacement
isolation block..
