MAIN AMPLIFIER 4xUHF+VHF/FM/AUX AGC 118dBuV

WWK ALPHA+ is a new-generation digital and selective amplifier. TELKOM-TELMOR has designed and manufactured it using the latest available technologies:

• High selectivity + 32 filters
• High gain + AGC (Automatic Gain Control, automatic gain adjustment)
• Protection against unwanted signals (LTE, 5G)
• Best possible output signals, no unwanted signals

The WWK-ALPHA+ programmable main amplifier is an excellent choice as a television signal amplifier, but also for other signals using additional inputs AUX, DAB, and FM.

The amplifier features an adjustable output level of 98 - 118 dB?V and additional tilt adjustment.

Each DVB-T/T2 signal can be programmed individually according to input and desired output frequency and output level. Additionally, it is possible to check output power levels on selected frequencies (dynamic measurement).

Installation and parameter settings are performed locally using the amplifier's own control buttons, and selections are visible on a large VFD display (2x16 characters).

If needed, LTE channels at 700 and 800 MHz frequencies can be filtered, and power can be supplied to inputs 1-4 (VHF/UHF) connected preamplifiers.

A test point with 30 dB attenuation enables measurements using basic meters or connecting the signal to an optical distribution system without additional attenuators.

The compact housing and external power supply allow the device to be installed in various types of mounting cabinets.
