Alcad AM-374 LTE preamplifier

The amplifier is very efficient in processing the received signal so that you can watch the entire channel range without any drop-outs. Don't limit yourself in placing the amplifier wherever it suits your requirements. It is also suitable for outdoor installation, due to the increased resistance to weather conditions and vibrations. The amplifier can be mounted to a mast (using the supplied shackle) as well as on the wall.

Every input has a separate output level control, so you can easily adjust the optimal signal gain level. It also suppresses the disturbing LTE band. The amplifier is powered with a coaxial cable. It is manufactured by SMT technology and is located in the Zamac casting. The electrical and mechanical interconnection between the PCB and the Zamac casting is improved, resulting in greater stability of the amplifier.
