The LNA-177 preamplifier has been designed for mounting in antenna box, directly to antenna connectors (300 ohm, balanced). It is ideal device for amplifying weak signals with low S/N ratios.
The amplifier works in BIII, IV, and V bands. The metal housing shields the device and restricts electromagnetic interference. The amplifier is CE certified.
