The main advantage of the SA-91L model is the ability to build very extensive networks that can count even several hundred reception points while maintaining the highest signal quality. Precise gain adjustment is performed using step switches (every 1 dB), which guarantees exceptional parameter stability over time and eliminates the risk of system misalignment. Additionally, the cable slope pre-correction function allows for the compensation of losses resulting from the length of coaxial cables in the installation.
The device is characterized by extraordinary resistance to interference thanks to the use of a die-cast housing with a high shielding class (class A). This is particularly important in times of dense development and a large number of wireless signals (LTE/5G) that could negatively affect the quality of the distributed image. The SA-91L is the heart of a modern antenna installation, ensuring the stability of 4K Ultra HD and Full HD signals at every outlet in the building. Thanks to advanced electronics, the amplifier minimizes self-noise, which translates into a crystal-clear image and sound without stuttering. Mounting the device is intuitive thanks to clear input and output markings, and the compact dimensions allow for easy installation in RACK cabinets or telecommunication boxes.

The SA-91L multiswitch trunk amplifier is a professional device designed by the renowned company TERRA, dedicated to operation in extensive terrestrial and satellite television collective systems (SMATV). This device is a key element of installations based on 9-input multiswitches, where there is a need to amplify and precisely equalize signal levels before their further distribution to subscriber outlets. Thanks to the use of 8 satellite inputs and one input for the DVB-T/Radio signal, the amplifier allows for comprehensive support of two satellite positions and the full terrestrial television band.
