Ref. 561521: Amplificateur NanoKom, 3 entr?es: BIII/UHF-FMcoupl?-BIScoupl? ? ?
Amplificateur de m?t qui amplifie et couple les signaux de television terrestre et satellite provenant de diff?rentes antennes.
Il poss?de 3 entr?es: Les signaux BIII/UHF sont amplifi?s alors que la FM et la BIS (SAT) sont uniquement coupl?s.
Passage de courant sur l’entr?e satelllite pour alimenter le LNB.
Ref. 5796: PicoKom power supply (for FImix) 12V – 220mA, 1 output
12V (220mA) source, which sends power through the input coaxial cable, allowing the TV signal to pass through. It is sandwiched in the installation to power mast amplifiers or a BOSS system. It is compatible with amplifiers with satellite mixing (FImix), as it automatically detects the existence of an LNB management signal (voltage and tone) generated by a receiver at its output, and lets it pass to its input.
Stands out for
They incorporate “USOS” (User Selectable Output Signal) technology: the installer selects the desired output level, which remains stable. The device adjusts automatically to adapt its gain to variations in the input signal.
Separate amplification and very low noise figure, thus respecting the signal quality
Ultra-slim ergonomic design
EasyF connection system
They can be powered from 12 to 24V
Fully automated manufacturing subjected to rigorous quality controls
High armor chassis, made of Zamak
Main Features
LTE700 / 5G filter to eliminate telephony interference
ON / OFF switch to allow DC through to UHF input, to power a BOSS system
Simple assembly. Flange for fixing to the mast included
Durable orange ABS plastic housing for outdoor installation
EasyF connection system: simplicity and savingsThe EasyF is an innovative concept of connection of the internal conductor of the coaxial (live) cable, which is inserted directly into the device increasing the reliability of the connection. Furthermore, 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: speeding up the installation is possible, as it is not necessary to make the connectorization of the coaxial cables. In addition, the process of threading the connectors on the device is avoided, which is sometimes complicated when space is not enough.
Connection reliability: the cable tie that holds the cables prevents the coaxial from loosening
Cost savings: no additional connector (neither “F” nor “CEI”) is required
Space optimization: inputs and outputs are always located on the same side of the device, avoiding bending the coaxial cables and facilitating work inside cabinets and registers
Very simple assembly in three steps: you only need to screw and unscrew the covers 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 cover and screw to secure the connection
Find out more about the reliability of the EasyF system
With EasyF, the connection of the coaxial cable in the device is made by means of an automated system of insertion of the live (internal conductor) by contact, without requiring soldering.
Like the first day: the life of the device increases by eliminating the possible deterioration of the welds with the passage of time
Reduced failure rate: generally caused by cold welding
Optimization of electromagnetic behavior: 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
