SKAITMENINIS KANALŲ STIPRINTUVAS WWK-ALPHA+ TELMOR

WWK-ALPHA+ is a digital selective amplifier. This device will be the best choice as a first active device in terrestrial television signal distribution network and other signals (e.g. using ports AUX, DAB, FM).

Each DVB-T/T2 signal can be configured separately according to input and desired output frequency as well as output level. Additionally, it is also possible to check the output power level at selected frequencies (dynamic measurement). Installation and parameter adjustment are done by local manipulator and are visible on large display.

The device has a built-in LTE,5G signal filter that eliminates unwanted signals in the 700/800 MHz band intended for the implementation of data transmission services (LTE,5G). Thanks to the possibility of powering the preamplifiers, it is not necessary to use power inserters in the case of using active antennas. (VHF/UHF1-4). Test point with 30dB attenuation will allow you to use it for measurements on simple meters or for connecting the signal to optical distribution systems without additional accessories in the form of attenuators.
