Receiver WZ LSA 4-3/G

WZ LSA 4-3/G

Light-signal system receiver for the 4 m band in IP65 housing 

For the radio control of light-signal systems, we offer the receiver WZ LSA 4-3/G in the frequency range 68 – 87.5 MHz.

The receiver is equipped with a frequency synthesizer. One of the pre-programmed frequencies can be set on site using the DIP switch. No crystal change necessary. If more frequencies are required, the frequency in the processor can be changed via a source code.

Additionally, we offer an analog field strength output in this version.


  • Quick detection of the ideal position
  • Recognition of occupied channels
  • Possibility to establish squelch circuit to prevent misinterpretation due to noise.
