It's an IEC 169-2 connector and since there's no impedance matching then
I doubt the presence or absence of a terminator will make much
difference. Ideally you'd be recommended to replace them with F
connectors, as commonly used with satellite TV, which do impedance
matching and therefore offer less signal distortion (keeping the
standard connector only for connecting to the card/TV).
There's some stuff on the IEC 169-2 connector on Wikipedia:
