Terrestrial line amplifiers with return path. To be used as the final amplifier before wall outlets. Normally used to amplify signals in small distribution networks. These amplifiers can be used at the output of an optical link. All the adjustments are internally located under the die cast cover to prevent unauthorised access. The die cast cover is secured with safety screws. For installation, supports are available (item MBX0001 see page 64) that leave a space of 19mm between the amplifier and the wall, allowing room for cables or the amplifier to be mounted in different positions. Packaging 1 pc.
