Amplifiers with automatic gain control (AGC) can solve signal-shifting problems that occur in particularly critical areas.
Factors such as lowering or raising of tides, strong humidity or fog can cause instability of the received signal and therefore the impossibility of guaranteeing the correct operation of a TV system over time.
The amplifiers with AGC, available in the plug-in or mast version for TV antenna or as self-powered head-end, are equipped with a special circuit that can vary the gain according to the level of the received signal.
The detection of signal variations occurs on the whole band: in order to favour the good functioning of the AGC circuit, it is advisable to equalize the band signals by introducing equalized filters (code 83191CE).
The mast model and the self-powered head-end offer the possibility of connecting 2 VHF and UHF antennas, or, acting on the appropriate selector, the input becomes a single VHF + UHF.
Inside the amplifier there is a jumper to select the types of input: 2 inputs VHF/UHF or 1 single Log. The product has a good linearity over the entire amplified band, an excellent separation between individual inputs and an excellent signal/noise ratio.
All the amplifier series are made with
die-casting mechanics combined with tinning treatment;
die-casting F- connectors;
internal separators for high output level amplifiers.
The outdoor case protects the amplifier from atmospheric agents by means of a watertight closing system and allows a practical fixing of the connectors thanks to the tilting movement.
The electrical performances have a low noise figure and linearity of frequency response for all the many versions differing for inputs, gain and output level. They are ideal for DTT signals in the LTEfree 4G and LTEfree 5G versions.
The version with Automatic Gain Control (AGC) or the version with Intermodulation Control (CI) is available.
