MAST BAND AMPLIFIER
SERIE AMB 600-N
DESCRIPTION
Broad band amplifier, suitable for individual systems or small
installations in low signal level areas. Operates with a wide range of
input levels.
The circuit, which is housed in a metal box, provides a high degree
of isolation between inputs and outputs, as well as immunity from
radio-electric interference.
The set is covered with a plastic housing, which protects it from
ultraviolet radiation and bad weather conditions. The housing is
designed for easy fixing on the mast.
• Direct antenna connection. Very low noise figure.
• Independent level regulation for each input.
• Notch filters for selective level regulation of two UHF signals.
• Protected against atmospheric disturbances and radio-electric
interference.
• Connection point for output level TEST.
• Designed with SMD technology
