The MA081L mast amplifier by Terra is a device dedicated to individual installations or small collective installations for several dozen sockets. Its main task is to raise the signal to such a level that it is possible to receive it on several or several receivers. The amplifier has inputs: FM + VHFIII band signal (88-108 MHz + 174-230 MHz) and 2xUHF band (470-790 MHz). The gain in the FM + VHFIII bands is 20 dB, while in the UHF band it is 30dB.

The MA081L amplifier has a built-in LTE signal filter that enables the elimination of unwanted signals in the 800MHz band (791- 862 MHz frequencies) for the implementation of data transmission services (LTE).
The cast housing ensures high screening efficiency, preventing the penetration of interfering signals inside the device.

Due to the supply voltage of 12 V, the MA081L amplifier can be powered from a typical power supply with a 12V / 100mA separator. It is also possible to supply power from amplifiers which supply power via coaxial cable. The MA081L R82023 amplifier has a low noise level.

Distinguishing features:
- 12V 60mA power supply
- LTE signal attenuation (band> 790MHz)
- 20 dB gain in FM, VHFIII band and 30dB gain in UHF band
- gain control with a potentiometer
- die-cast housing inside a compact plastic housing
