Details
Masthead antenna amplifier Terra MA080L R82022 is dedicated for outdoor applications in individual antenna installations and small MATV systems (without an additional launch amplifier - up to a dozen outlets). It has FM (88-108 MHz), VHFIII (174-230 MHz), and UHF (470-790 MHz) input. The maximum gain is 20 dB in the FM and VHFIII bands, and 30 dB in the UHF band.
Thanks to built-in LTE filter (791- 862 MHz), the MA080L R82022 amplifier can be used in environments where LTE services cause problems with the reception of DVB-T broadcasts.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the device. The amplifier also features low noise levels.
The amplifier can be powered from a typical AC/DC adapter (12VDC/100mA) with RF/DC isolator, or from a launch amplifier with 12 VDC power option for an preamplifier.
Key features
- power: 12 VDC, 60 mA
- LTE filter (attenuation of signals over 790 MHz)
- max gain of 20 dB in FM and VHFIII bands, 30 dB in UHF band
- gain adjustment with potentiometers
- small size cast metal case put into compact size plastic housing
