The MBA 435 N has been designed to amplify terrestrial TV and radio signals for installations and distribution systems. The
MBA 435 N has separate inputs for the different terrestrial frequency bands.
The different signals can be levelled individually.
The MBA 435 N offers
4 Inputs (FM, DAB, UHF 1 and UHF 2)
DAB, UHF-1 and UHF 2-Input with 12 V/24V 150 mA supply for antenna pre-amplifiers
2 Outputs (1 Output -30 dB)
Integrated, replaceable power supply
The output can be connected to the terrestrial input of satellite multi switches in order to further distribute the signal.

3. Configuration of the MBA 435 N
FM Antenna Input 1
Connect the cable of a FM antenna (88 - 108 MHz) to this input. If the input is not connected, it must be terminated with
a 75 Ohms resistor.
DAB Antenna Input 2
Connect the cable of a DAB antenna (174 - 240 MHz) to this input. If the input is not connected, it must be terminated
with a 75 Ohms resistor.
UHF 1 Antenna Input 3
Connect the cable of an UHF antenna (470 - 694/862 MHz) to this input. If the input is not connected, it must be
terminated with a 75 Ohms resistor.
UHF 2 Antenna Input 4
Connect the cable of an UHF antenna (470 - 694/862 MHz) to this input. If the input is not connected, it must be
terminated with a DC blocked 75 Ohms resistor.
Grounding Clamp
5
Connect a qualified earthing cable to this connector. The earthig cable must be connected to ground.

Terrestrial Multi Band Amplifier MBA 435 N
DC LEDs
the DC LEDs indicate the DC supply to the connected antennas. If the LED is OFF then no DC is supplied to the related
input. If the LED is green, then 12V are supplied to the related input. If the LED is orange then 24V is supplied to the
related input.
DC Supply Switches
Wit the DC Supply Switches you can set the DC supply to the related inputs. You can select to supply no, DC (Off), 12V
or 24V @ 100mA to the input, depending on the requirement of the connected active antenna.
7
Band Selection Switches
Wit the Band Selection Switches you can set the allowed input frequency range to the UHF inputs. You can select to
support 470 to 694 Mhz or 470 to 862 Mhz for each UHF input separately.
8
Gain Adjustment
Wit the gain adjustment you can set the gain of the related inputs to make sure, the output levels of all inserted
terrestrial bands are equal.

Output
This output offers the combined signals of the different inputs. The signal level of 118 dBµV is sufficient to distribute the
signal to several antenna sockets. You also can insert the combined signal on this output to the terrestrial input of
satellite multi switches where it can be further distributed.

Test Output (-30 dB)
This input serves the installer to measure the level of the different signal sources. Here you can connect a measurement
device to level the signals of the different bands.
