Adjustable Terrestrial and Cable TV Signal Amplifier Spacetronik SPA-28SG LTE II

The Spacetronik SPA-28SG LTE II is a high-performance adjustable terrestrial and cable TV signal amplifier designed to enhance DVB-T/T2 and CATV reception. With a built-in LTE/5G filter, it effectively suppresses interference from mobile networks, ensuring clear and stable signal transmission. The amplifier features adjustable gain from 10 to 28 dB, allowing precise optimization for various signal conditions. Its compact metal housing is suitable for indoor installation, and the built-in power supply simplifies setup.

Advantages

This amplifier offers exceptional flexibility with its adjustable gain control, making it ideal for both weak and strong signal environments. The integrated LTE/5G filter (up to 694 MHz / C60) protects against interference from cellular networks, while the two outputs enable distribution to multiple devices. The low noise figure (<4 dB) ensures minimal signal degradation, and the F-type connectors provide reliable connectivity.
