Details
The Terra MA-049L R82325 building amplifier has been designed for individual or shared antenna systems with up to a dozen or so outlets. It is used for increasing the signals from antennas to the level necessary for distributing them to a number of televisions in the house. The amplifier has individual inputs for FM (88-108 MHz), VHF III (174-230 MHz) and UHF (470-790 MHz) bands. The maximum gain in the FM and VHF III (BIII) bands is 30 dB, whereas in the UHF band is 34 dB. The maximum output level is 112 dBμV (IMD3=60 dB), suitable for distributing the output signals to a dozen or so outlets.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
The MA-049L R82325 amplifier has been equipped with ON/OFF switch that in the ON position enables powering a UHF preamplifier with 12 VDC (the maximum current cannot exceed 60 mA).
The R82325 amplifier is especially recommended for broadband antenna systems, where amplification of the UHF band should be limited to 790 MHz due to LTE services. The amplifier is equipped with built-in LTE filter limiting the unwanted signals above 790 MHz (791-862 MHz) that are reserved for the services.
Key features:
- integrated LTE filter
- 30 dB gain in FM and BIII band, 34 dB in UHF band
- ON/OFF switch enabling in ON position to power UHF preamplifier with 12 VDC (max 60 mA)
- die-cast housing ensuring high screening efficiency that prevents penetration of interfering signals to the unit
