Key features
- built-in cable-loss correction,
- integrated LTE filter,
- split-band circuitry with separate gain adjustments in FM and BIII (30 dB), and UHF (34 dB) ranges,
- switchable (ON/OFF) 12 VDC / 100 mA supply for a preamplifier,
- die-cast housing for highly efficient screening to prevent the penetration of interfering signals into the unit.
Terra's MA050L R82050 house amplifier is dedicated for use in small shared antenna systems with more than ten outlets, e.g. in single-family and multi-family homes. Its basic role is to amplify the signal so that it can be picked up by several or more receivers. The amplifier has separate inputs for FM+VHFIII (47-108/174-230 MHz) and UHF (470-790 MHz) bands, with a max. gain of 30 dB in the former, and 34 dB in the latter.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the unit.
MA050L R82050 enables switchable (ON/OFF) 12 VDC/100 mA power supply to a preamplifier. The maximum output level of 115 dBμV (IMD3=60 dB) allows for secure signal distribution to more than ten outputs. The built-in compensation of cable attenuation (slope) equalizes signal levels within the whole band by increasing the gain for higher frequencies.
MA-050L R82325 is particularly recommended for systems using broadband amplifiers (up to 790 MHz). The application of the split-band amplifier eliminates the risk of interference from 800 MHz 4G LTE networks, thanks to a built-in LTE filter blocking signals within the 791-862 MHz range allocated for this kind of wireless services.
