TRIAX TMA 447 LTE Multiband Amplifier

Product Number: 324447

The TRIAX TMA 447 LTE is a professional multiband amplifier designed for selective amplification of different broadcast frequency bands in MATV and SMATV distribution systems. It provides precise control of FM, Band I, Band III, and multiple UHF inputs, while ensuring strong protection against LTE/5G interference by limiting UHF bandwidth to 694 MHz. With adjustable attenuation, test monitoring capability, and remote powering support for preamplifiers, it is ideal for advanced TV signal distribution networks in residential and commercial installations.
