Weak signals can be received with this antenna. They incorporate DC paths to permit the feeding of a preamplifier. The environmental temperature is the temperature of the air at a distance of more than 1m from the equipment or from the cabinet in which the alcqd is installed. Does not include the accessory for the transmission of IR signals compatible with the digital receivers.

The number of modules it can power varies, depending on the consumption of the modules. Connection to the antenna by means of fast-on connections and to the coaxial cable by means of a screw terminal. Power supply jack, 9. F type connectors in nickel-plated iron which affords a connection of minimum mismatching and maximum shielding. Orders should indicate the number of multiple packs vf not the number of antennas.

The electrical characteristics are identical to those of the equivalent products, except for the feed voltages. The built-in power supply unit can automatically feed a preamplifier. CODE Further specifications on the following page. The inputs of the 4 polarities and the terrestrial TV are amplified.

This adaptor enables standard electrical boxes with DIN rail to be used for the TV connections panel. PR Characteristics Shielded zamak chassis, with female input and output F connectors. The output level is controlled through the gain control of the monochannel alvad. Modulator with mono audio in VSB vestigial side band, designed to work with adjacent channels. Secured to the roof by means of a mast base for roof-tiles, to the wall by means of two brackets or to the chimney alcae means of a special clamp.


Characteristics Return path included from 5 to 65 MHz.

They incorporate a DC path to permit the feeding of a preamplifier. Suitable also for installations in which it is necessary to convert the frequency of 7 the digital channels. 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. Any combination of channels can be treated, including adjacent channels with monochannel or multichannel treatment. Supplied with power cable alcxd amplifier and 10 modules, or 11 alcadd.

Connection of power supply by means of ribbon cable with pin polarised connectors. Equipped with gain control and independent equaliser for each polarity. The distribution is made in a star-shape using the two outputs of the amplifier and splitters. The noise level is extremely low in order to amplify the signals without losing quality. Characteristics 3 4 Shielded zamak chassis and F type connectors.

By dividing the installation into lines of outlets and distributing the 4 or 8 polarities and the terrestrial TV to all the lines, it is possible to reach more than 2, outlets. Supplied in a multiple pack. Applications Large digital and analogue terrestrial MATV installations where the group of adjacent digital channels is incorporated.

The gain control of each input of the amplifier permits the adjustment of the levels of each antenna.

Characteristics Shielded zamak chassis, covered by an ABS plastic box for outdoor use. The dish is made of polyester with an inserted metallic mesh.


Alcad Catalogue – TOPMODE –

The antenna preamplifier is used when the signal level is very low. Each product includes two equalisers which can be used independently or in series.

They have a DC path from one of their outputs to the input and from the through output in the intermediate outlets to the input. Connection of power supply by means of flat cable with pin polarised connectors. Several sections can be assembled telescopically to make a longer mast. Permits the installation of equipment with a power supply unit and 12 modules. Applications Designed for use in large, digital and analogue terrestrial MATV installations which require an amplifier adapted to the specific needs of the area.

Due to the difficulties in compiling this information and to the variations which these standards are continuously subjected to, this information should be used as a guide only. In this way the intermodulation is reduced in the broadband amplifier and an improved output level is obtained. Each input of the multiplexers has a low or high pass filter for a group of channels. The cables are then tensed so that the mast is perfectly vertical.

The power supply unit is insulated from the rest of the high frequency circuit, complying with the safety regulations for the installer and the user.

The filters should be separated by 4 channels. The frequency or output channel is programmable and any TV channel may be selected, including the interbands. The output level can be controlled by means of an attenuator.
