TV Antenna Socket Samsung

Hello
it's not clear whether it's flat, and if it screws in (coaxial satellite) then it's a male satellite connector
it all depends on the type of connector you have, but there are female adapters (to connect your male end to female to then plug into the device... or into the wall
this cable won't be necessary for TNT or a standard rooftop antenna like a dipole
it's only for installation on a satellite dish or satellite box.

Hello, I have the same issue, do you have the solution?

Good evening,
Is it an old 9mm cable?
There are indeed adapters from 9 to 9.5mm

a priori everything is normal
which socket do you want to connect your cable to? ANT1 or ANT2,
Is the cable connected to a wall socket?
Is it the one whose diameter is too big or too small?

Are you sure it's the antenna cable?
