Connection to the antenna by means of fast-on connections and to the coaxial cable by means of a screw terminal.
Each band has a gain control and a variable equaliser. Each module consists of 3 input filters, frequency converter and 2 output filters, which are cavities for high frequencies.
Each outlet of the installation receives the terrestrial TV and any of the satellite polarities, which are selected from the individual satellite receiver. Designed to cover all the UHF band with maximum flatness. Gain and noise figure after applying gain reduction by diplexing.
CF-112_ distribution amplifier – return path
Characteristics The output channel can be selected by means of switches. Consisting of a power supply unit, and amplifier cd up to 8 zlcad, which are mounted on a support frame. The arborescent distribution reduces the number of distribution elements and the length of coaxial cable to be installed, even though the distances from head-end to outlet remain constant.
Power supply unit for multiswitch, 18 mA. It has one input to amplify the IF signal coming from all the processors of the installation, and a terrestrial band multiplexing input for the rest of the channels of the installation. The power supply units are protected against overloads and short circuits.
They are fed through the coaxial cable from a power supply unit installed inside the building. Alad dividing the installation into lines of outlets and distributing the 8 or 16 polarities and the terrestrial TV to all the lines, it is possible to reach more than 2, outlets. With the SP frame it is possible to mount up to 18 modules. The signal obtained can lacad distributed to a large number of TV outlets using a single coaxial cable.

The frequency output channel is programmable and any TV channel can be selected, including interband channels. They cover alcadd between 5 and MHz. Designed to permit cc distribution of the IF band among groups of different buildings or houses from one single SAT head-end. The guy wires are fixed to the tower by means of wire rope grips so that the tower is held perfectly vertical.
Characteristics Protected against power surges, overloads and short-circuits. Channel converter equip- 6 ment to organize the spectrum according to our needs. Any delay in the agreed date of payment could be cause for an additional invoice to cover the costs of delay and damages.
Amplifies and mixes the signals alcaf several antennas. There is a high carrier to noise ration, which makes it possible to combine head-ends of up to channels. Df Digital MATV installations where it is necessary to distribute digital terrestrial channels which have been converted to analogue channels. RF 75 W load for screw terminal. Modulator with mono audio in VSB vestigial side band, designed to work with adjacent channels. The antenna is an offset type with high gain and efficiency.
The filter enables the elimination of the audio or video carrier of the interfering signal, a higher rejection level can be achieved adjusting several filters to the same carrier. BM Characteristics Voltage blockage in the output connectors.
Installation as a terminal outlet connected to a tap-off or splitter, or as outlets in series connected to each other. A control voltage can be sent in installations of multiswitches through their outputs. LA 1 Units per packing 0,01 Kg Packing weight 1112 dimensions 80 x 70 x 20 mm Power cable LS 12 Units per packing 0,04 Kg Packing weight Packing dimensions x 45 x 20 mm Long power cable Units per packing Packing weight Packing dimensions Long power cable, to feed a separate module.
Also it is possible to assemble equipment with 2 power supply unitsan amplifier and 8 modules, or 2 power supply units and 9 modules. The levels for broadband amplifiers are also specified according to the DIN B norms as are the levels for monochannel amplifiers in norm DIN K.
Applications EQ Used as a complement to a distribution amplifier to give a greater equalisation before amplifying it, especially after long runs of cable. The main advan- 10 tage of this equipment is that all the filters can be programmed rapidly and adjusted automatically. Fed by a built-in power supply. The new vandal proof entrance panels range by ALCAD is the best option if you are looking for a durable and reliable solution that suits all needs.
Especially appropriate as an apartment amplifier in cable TV networks or in community installations where the interband bands are used. Characteristics GA The electrical characteristics of the antennas in a multiple pack — pre-mounted or dismounted — are identical to those of equivalent models. Permits the independent reading of both sides of the installation. Programmable with programmer PS version 3.

The generated channel is mixed with the rest of the channels of the TV installation. It allows the distribution of vf terrestrial TV and satellite signals in a unified form from a single piece of equipment. F connector 2 output splitter.
The number of modules which it can feed varies according to the consumption of the modules and of the consumption of the LNBs in the case of SAT amplifier modules.
They mix the signals from several antennas in a single coaxial cable. Fixed to the wlcad by means of the supplied screws and wallplugs. Characteristics The electrical characteristics are identical to those of equivalent products, except for the range of frequencies of the return and direct paths.
Independent housings for the power supply unit and the high frequency circuit. The channel group models make it possible to optimise the gain of the antenna for each group, obtaining a better response than with broadband models.
