WWK ALPHA+ is a new generation selective (channel) amplifier. Developed by TELKOM-TELMOR based on the latest technologies that provide:
- high selectivity with 32 filters
- high gain with AGC
- protection against unwanted signals (LTE, 5G)
- excellent quality of the output signal, free from unwanted signals.
The device will be an ideal first element of the distribution network of terrestrial TV signals and others that we plan to introduce to this network (e.g. via AUX, DAB*, FM ports).

Provides optimal output level adjustable in the range of 98..118dB? V (with possible slope correction).
Each DVB-T/T2 signal can be adjusted independently in terms of input and output frequency, as well as output level. In addition, we can read the input power level at selected frequencies (dynamic measurement). Installation and adjustment of parameters is carried out using a local keypad and a large VFD display (2x16 characters).

There are also the possibility of filtering LTE channels from the 700 and 800 MHz bands and the possibility of powering antenna preamplifiers connected to ports (VHF/UHF 1..4).

The test point with 30dB attenuation will allow it to be used for measurement on simple meters or to connect the signal to optical distribution systems without additional accessories in the form of attenuators.

The slim housing and external power supply will allow you to fit the device in any mounting cabinet.
