The Alcad AM155 is a single-entry mast amplifier in a new, improved design, with increased weathering and vibration resistance. Suitable for indoor and outdoor installation. Individual inputs have separate regulation of gain by resistance trimmer, power supply amplifier + 12V is realized remotely via coaxial cable through the output, original power supplies are AL-105 or AL-205, which are including power switch and have integrated broadband hub, amplifier is manufactured by SMT technology and placed in Zamac casting, plastic cover provides increased protection against weather conditions, plastic amplifier cover is adapted for mounting on mast (max. diameter approx. 48mm using black PE strap) as well as on the wall, inputs and outputs are on F-connectors, UHF inputs can be switched on for + 12V / 50 mA preamplifiers, electrical and mechanical connection between PCB and Zamac casting is improved, resulting in greater amplifier stability.
