MAST BAND AMPLIFIER AMB 800 Series Professional mast band amplifiers, immune to all signals from other services which share the radioelectric spectrum, such as mobile phones, wireless transmissions, terrestrial communications.... APPLICATION Suitable for individual systems or small installations, with high sensitivity and output power (114 dBV), the AMB 800 is a heavy-duty amplifier, ideal for future applications according to new Digital Terrestrial TV (DTT) requirements. It is prepared to process both analogue and digital signals during the migration towards DTT. CHARACTERISTICS Very low noise figure and independent from gain regulation Test point at -30 dB that allows level control without interrupting remote power and function. The mechanical solution guarantees an exceptional immunity against noise invasion, a critical aspect for DTT reception. 3 Notch filters can be adjusted over the whole UHF band, or even in their extremes to achieve an additional rejection to unwanted signals.
