How to use: Connect the antenna to the splitter as per the basic connection guidelines. Since there's no power supply, you'll need to arrange your own suitable power source. Before connecting, make sure all devices are turned off. When using, keep the splitter in a well - ventilated area. Attention: Always double - check the power compatibility when using your own power supply. Avoid exposing the splitter to water or excessive moisture. Maintenance advice: Regularly clean the splitter with a dry, soft cloth. If you notice any issues, don't attempt to repair it yourself. Instead, contact a professional technician.
