Description

The AB-011 masthead amplifier from Terra is a professional device designed to optimise the reception of terrestrial digital television DVB-T and DVB-T2. It is an ideal solution for users struggling with weak signals or image interference. By mounting it directly at the antenna, the amplifier eliminates signal losses occurring in the cable, which significantly improves reception quality. The device stands out from the competition with an extremely low noise figure of less than 1dB, allowing for a clear image even in difficult terrain conditions.

Another key advantage is the innovative power supply system – the amplifier can operate at 5V, which is standardly provided by most modern decoders and televisions at the antenna input. This eliminates the need to install additional power supplies and separators, simplifying the entire installation and reducing costs. A solid metal inner housing provides excellent shielding against external interference, while the outer plastic cover protects against rain and sun.

The amplifier offers two gain levels (14dB or 27dB), selectable via a simple switch, giving the installer full control over the signal strength at the sockets. This product guarantees stable reception of all available multiplexes, including HD and 4K quality channels, without annoying transmission interruptions. By choosing the Terra brand, you are opting for European quality and many years of trouble-free operation, confirmed by a two-year warranty period. It is an indispensable element of any efficient antenna installation in a single-family home or small guesthouse.

Specification

Frequency range

470 MHz ... 862 MHz - The device operates in the full UHF band range, which allows for the reception of all terrestrial digital television multiplexes available in Poland, including the latest broadcasting standards.

Gain

14 dB / 27 dB (switch) - The amplifier has a built-in microswitch that allows for selection between two gain levels. This enables signal optimisation depending on the distance from the transmitter and avoids receiver head overload.

Noise figure

< 1 dB - This is one of the most important parameters of the amplifier. Such a low level of self-noise ensures that the device does not degrade signal quality, which is crucial for stable HD and 4K channel reception.

Return loss

> 10 dB - High return loss indicates excellent manufacturing quality of the input and output circuits, which translates into no signal reflections and stable operation of the entire antenna installation.

Number of inputs/outputs

1 / 1 - The device has one input for connecting a UHF antenna and one output for routing the amplified signal to the receiver or the rest of the installation.

Maximum output level (IMA3 60dB)

108 dBµV - This parameter defines the amplifier's ability to deliver a strong signal without distortion. A level of 108 dBµV is sufficient to power an extensive home installation consisting of multiple sockets.

Shielding

Full electromagnetic shielding - The interior of the device is a solid metal casting that effectively blocks radio frequency interference (RFI) and electromagnetic interference (EMI), ensuring the purity of the transmitted signal.

Impedance

75 Ω - Standard input and output impedance value, fully compatible with all coaxial cables used in television technology.

Connector type

F-type connectors - The use of professional F-connectors guarantees a secure electrical contact and high mechanical resistance of the connection, which is important for outdoor installation.

Housing construction

Compact and resistant - The electronics are enclosed in a metal box, which in turn is inside a hermetic housing made of high-quality plastic, protecting against moisture.

Mounting

Mast or wall - Thanks to the well-thought-out housing design, the amplifier can be easily mounted on a mast pipe using the included cable tie or screwed directly to the building facade.

Operating temperature

-20 °C ... 50 °C - A wide temperature range guarantees reliable operation of the device during both freezing winters and hot summer days, without the risk of overheating or failure.

Power supply

4.5 V ... 12 V DC - An extremely practical function allowing the amplifier to be powered with 5V directly from a DVB-T tuner or a standard 12V power supply with a separator.

Power consumption

0.3 W - Extremely energy-efficient design. Low power consumption makes the device practically unnoticeable to the household budget and does not excessively load the power supply built into the decoder.

Manufacturer / Brand
