Podrobný popis
Terra's MA050T R81050 house amplifier TERRA is dedicated for use in shared antenna systems with several outlets, for example in single- or multi-family buildings. It is mainly designed to increase signal level so as to allow reception by several or even more receivers. The amplifier has the following inputs: FM+VHFIII signal (88-108/174-230 MHz) and UHF band (470-694 MHz). The gain in the FM+VHF bands is 30 dB, while in the UHF band it is 34.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the unit.
The MA050T R81050 amplifier has an ON/OFF switch to provide 12 VDC/60 mA power supply to an antenna preamplifier. The maximum signal output level of 115 dBuV (IMD3 = 60 dB) enables safe distribution to several outlets. The built-in compensation of cable attenuation (slope) equalizes signal levels within the whole band by increasing gain for higher frequencies.
The MA050T R81050 amplifier is recommended particularly for systems using broadband amplifiers covering the UHF band (up to 694 MHz). It has a built-in LTE signal filter that enables the elimination of unwanted signals in the 700 MHz band (694 - 862 MHz) for data transmission services (LTE).
Key features:
- built-in cable-loss correction
- integrated filter LTE 700 signal attenuation
- 30 dB gain in the FM and VHF bands; 34 dB gain in UHF band
- 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.
