Detalii
Terra's MA044M R82044 house amplifier is dedicated for use in shared antenna systems. Its basic role is to amplify the signal so that it can be picked up by up to several dozen receivers. The amplifier has separate inputs for VHFI+FM (47-108 MHz), VHFIII (174-230 MHz) and 2xUHF (470-862 MHz) bands, with a max. gain of 30 dB in the VHFI+FM and VHFIII, and 34 dB in the UHF bands.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the unit.
MA044M R82044 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 outlets. The built-in compensation of cable attenuation (slope) equalizes signal levels within the whole band by increasing gain for higher frequencies.
Key features
- built-in cable-loss correction,
- 30 dB gain in the FM and BIII bands; 34 dB gain in all UHF inputs,
- switchable (ON/OFF) 12 VDC / 60 mA power supply to a preamplifier,
- die-cast housing for highly efficient screening to prevent the penetration of interfering signals into the unit.
