The plug for the socket to be read as in other reviews, in fact a little too short. A firm grip on the antenna socket is thus not guaranteed. Another star deduction.
It does what it should with me. The second TV receives a signal with little signal loss.
However, one need not have hope that there is a weak innately signal amplified so that the image quality increases significantly. Therefore, it is not suitable. Was it also not thought to myself, and therefore no additional reduction.
