The RCA AMP1450R Digital Signal Amplifier for Indoor Antennas helps enhance the performance of all passive indoor antennas. It was engineered specifically for digital signals but it also supports analog signals. If your antenna is in a quirky or challenging area, the AMP1450R will easily transmit a signal that’s crisp and clear. It optimizes signal for the best possible reception through improved gain and also preserves signal purity with Extremely Low-Noise (ELN) circuitry.
