TV signal amplifier for two TVs (Martlesham IP12)

Labgear aerial amplifier with outputs for two TVs. Needs mains power. For indoor use, but could be in a loft. There are two coax sockets on the white box, one is the aerial input and the other is one of the two TV outputs. There is a coax cable permanently attached to the box, and this is the output for the second TV. It works well but hasn't been used for some time. It will work with digital TV transmission.
