An antenna amplifier enhances the signal strength received or transmitted by an antenna. The necessity for its application arises when signal attenuation, caused by distance, obstructions, or cable losses, significantly degrades performance. A common instance is compensating for signal loss in long coaxial cable runs connecting an antenna to a receiver.
Employing a signal boosting device can significantly improve signal-to-noise ratio, resulting in clearer audio, sharper video, or more reliable data transmission. Historically, these devices have been vital in broadcasting, amateur radio, and satellite communications to overcome limitations imposed by distance and atmospheric interference. Their usage extends to improving cellular reception in areas with weak coverage.
