Antennas
High Power: Its RF output power can be as high as 30dbm. Compared with similar card readers, it has more output power. It supports RS232, RS485, and Wiegand interfaces, so it can work with most devices. Good Effect: It is equipped with an 8dbi antenna, and its effect distance can reach 6m~8m. So within eight meters, it can read the card clearly and ensure the quality of work. Multiple Working Modes: It supports automatic operation, and interactive and triggered working modes. In different situations, you can choose according to your needs. Power-saving: It uses a single +9V DC power supply, which can reduce power dissipation. It operates at high power while minimizing power loss.
