Detaily
Masthead antenna amplifier Terra MA081T R81081 is dedicated for outdoor applications in individual antenna systems and small MATV systems distributing the signal to tens of outlets. 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+VHF band signal (88-108 MHz + 174-230 MHz) and 2xUHF band (470-694 MHz). The gain in the FM+VHFIII bands is 20 dB, while in the UHF band it is 30 dB.
The MA081T R81081 amplifier has a built-in LTE signal filter that 700 enables the elimination of unwanted signals in the 700 MHz band (694 - 862 MHz) for data transmission services (LTE).
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals into the device.
Key features:
- power supply 12V 60mA
- LTE signal attenuation (> 694MHz)
- 20 dB gain in the FM, VHF band, and 30 dB in UHF band
- gain control*
- small size cast metal case put into compact size plastic housing
