General description

The SZI 1015-TW is a 2-Watt radiator with a coverage area of up to 400 m² in white finish. The radiator is switched on and off automatically by the modulator’s RF carrier. The RF signal from the modulator can be daisy-chained via BNC sockets. A barrier strip with RF and DC inputs and outputs is connected in parallel. The radiator has a 5/8” thread and comes with a 3/8” and 1/2” adaptor, it can therefore easily be mounted to various attachments.
