The SAC 4-Way LTE Masthead Amplifier Kit is a UHF masthead amplifier with a built-in 4-way splitter, delivering 10–25dB of variable gain across channels 21–60 (470–790 MHz). LTE/4G protected to prevent interference from mobile signals, making it well suited to areas with strong 4G coverage nearby. All four output ports are DC powered, allowing the unit to be powered via the coax feed from an indoor power supply unit. The fully shielded, waterproof housing with tight seal construction is designed for outdoor masthead installation. F-type connectors throughout. SMD circuit technology for reliable, consistent performance.
