Product description
Alcad AM387 is a three-input mast amplifier in a new improved design, increased resistance to weather conditions and increased resistance to oscillation. AM387 has a suppressed LTE700 band (it has a built-in 5G filter and amplifies UHF only up to 694MHz). The amplifier is suitable for installation in indoor and outdoor environments. Individual inputs have separate gain control with a resistor trimmer, the amplifier's +12V power supply is implemented remotely via a coaxial cable via the amplifier output, the original power supplies are AL-105 or AL-205, which include a power crossover and have an integrated broadband splitter. The amplifier is manufactured using SMT technology and is housed in a Zamac die-cast housing, the plastic housing provides increased protection against weather conditions, the plastic housing of the amplifier is suitable for both pole mounting (using the supplied bracket) and wall mounting, the inputs and outputs are F-connectors, and the UHF input can be switched on with a power switch for the +12V/50 mA preamplifier.
