Key features:
- integrated filter for LTE 700 signal
- 39 dB gain in the FM and BIII bands; 44 dB gain in UHF band
- switching between gain stages using discrete switches
- additional, smooth gain control with potentiometers
- smooth slope adjustment for the gain pattern
- switchable (ON/OFF) 12 VDC/100 mA power supply to a preamplifier
- die-cast housing for highly efficient screening to prevent the penetration of interfering signals into the unit
Terra's HS-004T HS-004T house amplifier is dedicated for use SMATV systems with several tens outlets. The amplifier one input for VHFI (88-230 MHz) and UHF (470-862 MHz) bands. The maximum gain in the VHF band is 39 dB, while in the UHF band it is 44 db. The built-in compensation of cable attenuation (slope) equalizes signal levels within the whole band by increasing gain for higher frequencies.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the unit.
The HS-004T R81131 amplifier has an ON/OFF switch to provide DC 12 VDC/100 mA power supply to an antenna preamplifier. The maximum signal output level of 121 dBuV (IMD3 = 60 dB) enables safe distribution to several outlets.
It is recommended particularly for systems using broadband amplifiers covering the UHF band (up to 694 MHz). The HS-004T R81131 amplifier 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).
