Low gain mast amplifier 3 inputs: BIII/DAB-UHF-UHF LTE790/700 and Televes Switchable DC Step

Mast installation amplifier to amplify terrestrial television signals coming from various antennas.

It consists of 3 inputs with amplification in all bands. The amplifier is powered at 12Vdc through the output coaxial cable.

It incorporates a switch for the selection of anti-LTE790 or LTE700 filtering.

Stands out for

• Separate amplification of each band
• EasyF connection system
• Fully automated manufacturing and subject to rigorous quality controls
• High armor chassis, made of Zamak

Characteristic

• Switch for LTE filter selection (790/700), to eliminate telephony interference
• ON/OFF switch to allow the passage of DC to one of the UHF inputs, to power a BOSS system
• Simple assembly. Flange for attachment to the mast included
• Strong orange ABS plastic box for outdoor installation

EasyF connection system: simplicity and savings

The EasyF is an innovative connection concept of the internal conductor of the coaxial cable (live), which is inserted directly into the device, increasing the reliability of the connection. In addition, thanks to the absence of "F" connectors, it is possible to reduce the chassis and secure the connection of two cables with a single screw.

• Real time savings: it is possible to speed up the installation, since it is not necessary to carry out the connectorization of the coaxial cables. In addition, the threading process of the connectors on the device, which is sometimes complicated when the space is not enough, is avoided.
• Reliability of connection: the clamp that holds the cables prevents the coaxial from coming loose
• Cost savings: no additional connector (neither "F" nor "IEC") needed
• Space optimization: inputs and outputs are always located on the same side of the device, avoiding bending coaxial cables and facilitating work inside cabinets and registers
• Very simple assembly in three steps: only screwing and unscrewing of the covers is required to connect two cables:

1. Unscrew the cover of the device to access the connection

2. Insert the previously stripped coaxial cables

3. Close the lid and screw to secure the connection

With EasyF, the connection of the coaxial cable to the device is carried out by means of an automated system for inserting the live (internal conductor) by contact, without requiring soldering.

• Like the first day: the lifetime of the device is increased by eliminating the possible deterioration of the welds over time
• Reduced failure rate: generally caused by cold welds
• Optimization of electromagnetic behaviour: at high frequencies
• Reinforcement of our commitment to the environment: pollution caused by the welding process is eliminated and electricity consumption in production is reduced

Why choose an amplifier with LTE790/700 switchable?

The anti-LTE filtering switch integrated in Televes amplifiers allows selecting the appropriate internal filter between channels 60 (790Mhz) or 48 (694MHz), adapting to the DTT channeling frequencies of the region, in such a way that it completely rejects the type of signal LTE that may interfere with the product.

This functionality offers the versatility to maintain an installation free of interference in all LTE situations, covering filtering needs in any territory with a single amplifier, before, during and after the transition period. In addition to this, it simplifies the logistics of the installation, only requiring the switching of the filter to adapt it to the Digital Dividend that operates in the region, and also allowing it to adapt to the contingencies that may occur in the execution of the dividend, in the form of delays or advances in planning.
