Amplifier Alcad ZG-421 is a channel amplifier for UHF band with IEC connectors on both inputs and outputs. When ordering it is necessary to specify for which channel the amplifier is required, it is possible to choose from frequency range 470 - 862 MHz. Under item 14430894 is specifically the Alcad ZG-421 C24 (for 24-channel) amplifier. Image is illustrative.

Channel amplifiers ZG / ZP are selective and powerful amplifiers designed for amplification of digital and analog TV / FM signal. They are part of a comprehensive system for the construction of STA / TKR main stations, which consists of amplifiers ZG / ZP (for UHF type 401, for I, III and S band type 601, for FM type 201), power supply AS-326 or AS -125 and accessories (mounting boxes and frames, preamplifiers, power switches, terminating resistors, jumpers). With its simple assembly, variability and high reliability, it is an ideal building block for common TV antennas and small cable distributions.
