    RECEPTION AND CAPTURE OF TELEVISION SIGNALS

    • Terrestrial Antennas

      Four ranges of terrestrial antennas are available: NEO (UHF), MX (UHF) , BU (UHF), BT (BIII, FM and DAB).

      NEO, offering the best gain on the market

      ANTENAS NEO is the highest-quality range offered by ALCAD, with the best DTT channel reception and the best gain on the market (18 dBi).

    Installation Examples

    HEADMAST AMPLIFIER WITH EQUALISER FILTER

    Headmast device for terrestrial TV comprising an equaliser filter and a broadband amplifier. Adjusting the attenuators of the equaliser filter equalises the levels of all the channels before amplification, meaning that the intermodulation in the broadband amplifier is reduced and a higher output level is obtained.

    Headmast device for terrestrial TV comprising an equaliser filter and a broadband amplifier. Adjusting the attenuators of the equaliser filter equalises the levels of all the channels before amplifying, meaning that the intermodulation in the broadband amplifier is reduced and a higher output level is obtained. The amplifier automatically feeds UHF antenna pre-amplifiers.

    INDIVIDUAL INSTALLATIONS WITH HEADMAST AMPLIFIER

    Individual terrestrial TV installation with amplifier and power amplifier mast used as a pre-amplifier. The pre-amplifier is fed from the amplifier. This configuration is suitable when the signal levels received are very weak.

    HEADMAST AMPLIFIER WITH STAR DISTRIBUTION

    MATV terrestrial TV installation with headmast broadband amplifier. The gain of each amplifier input allows you to adjust the levels of each of the antennas. The distribution takes place in a star pattern using the two amplifier outputs and distributors. This type of distribution allows the maximum number of outlets at the expense of using more coaxial cable.

    HEADMAST AMPLIFIER WITH TREE DISTRIBUTION

    MATV terrestrial TV installation with headmast broadband amplifier. The gain of each amplifier input allows you to adjust the levels of each of the antennas. The distribution takes place in a tree pattern using splitters. This type of distribution allows the signal levels to be balanced across all installations.

    INDIVIDUAL INSTALLATIONS WITH TV-SAT HEADMAST AMPLIFIER

    Individual terrestrial TV or satellite installation. The head amplifier is connected to a UHF antenna or an individual parabola, where signals are being received from several terrestrial TV antennas a mast mixer will be used. The LNB is powered and controlled from the individual receiver, through the amplifier.
