Low Power Transposer
General. The TZV -20 TV low power repeater is used to transpose a received input TV channel in I,III,IV or V band to another RF channel in the III frequency band. The output power is 20 Wps.
Digital compatible. The TZV repeaters are fully compatible with analog or digital TV signals.
Synthesized. The output RF channel can be easily set by an agile dip-switch selector.
Broadband. To change the output channel it’s simply necessary to retune the channel filter. All the other parts are broadband and don't need any retuning.
Precision AGC circuits guarantee high stability of RF output signal level.
Linearity built-in precorrector circuit optimizes the class amplifiers parameters.
Stereo/dual sound compatible. The RF bandwidth of the TZV permits mono, stereo or dual sound operations.
Offset configuration is available on request with precision up to 1 Hz.
Modular construction. For easy maintenance all circuits are built up in easily interchangeable plug-in modules.
Solar cells/battery power supply. Vdc power supply option is available for battery or solar cells operations.
Fully compatible with all international television standards.
Meets or exceed all FCC and CCIR requirements.
