Antenna amplifier ALCAD AM-187

The new series of AM amplifiers are 1, 2, 3 and 4 input broadband home amplifiers suitable for outdoor use. Individual inputs have separate output level control. The amplifier's +12V power supply is implemented remotely via a coaxial cable via the output. The amplifiers manufactured using SMT technology are placed in a Zamac casting, which is protected against weather conditions by a new, more durable plastic cover. Inputs and outputs are on F-connectors. The plastic cover of the amplifier is adapted for both pole mounting (using the included bracket) and wall mounting. For selected inputs, the +12V/50 mA preamplifier power supply is implemented via a switch. The new series has improved electrical and mechanical connections between the printed circuit board and the Zamac casting, which leads to greater resistance to amplifier oscillation. The AM-187 amplifier has an integrated 5G filter.
