TERRA MA077TB – 44dB-121dBμV (level DIN) High power multiband amplifier 5 input FM+B3+UHF+UHF+UHF/ 1 output
Description:
Multiband amplifiers are intended to amplify FM radio signals, TV signals in VHF (5-12 channels), UHF/BIV+BV (21-48 channels), UHF1/BIV (21-35 or 21-32 channels), UHF2/BV (36-48 or 34-48 channels).
There is a possibility to adjust the gain of the amplifier in every sub-band by fine turning 10 dB regulators and an additional 10 dB by switching switches in every sub-band.
The amplifier has possibility to feed external equipment only through input connector via on/off switch. Feeding for external equipment is short circuit and overload protected. If current used by external equipment is up to 0.1 A, an indicator glows green. When current increases, the protection circuit starts to operate and the voltage supply has being disconnected from external equipment. In this case the indicator glows red (overloaded).
The housing of amplifiers meets more stringent screening requirements according to EN50083-2, class A.
According to the standard ETSI EN 303 354 V.1.1.1, this amplifier type is Launch, selectivity classification O.
The amplifier is intended for indoor use only.
Features:
• High output level amplifier (push-pull) 5 input / 1 output
• For combining and balancing of the signals up to 5 TV antennas
• Integrated LTE signal suppression filter
• Protection and indication of DC overload
• Built-in attenuators for every band
• Switchable DC feeding for preamplifier through one UHF input
• Additional test point attenuation output
• Die-cast housing
