- W-410A is a fully automatic antenna switch in the shortwave band with ultra-low insertion loss and excellent isolation.
- It uses confirmed and stable RF Tester technology. Its switchinglogic is safe and reliable. In addition, it has two working modes: In the "4-M" mode, W-410A can be used for 4 radios to switch, using 1 antenna. It can automatically recognize the radio which is transmitting and completes switching without human intervention. In the "M-4" mode, it can be used to connect 4 antennas to 1 radio, and automatically switch to the antenna according to the radio transmission frequency.
- W-410A supports up to 200W RF power continuous operation, and has built-in 50u03a9 load resistors for all ports. In non-selected port status, switching to a 50u03a9 load resistor eliminates the need for users to worry about damage to the radio station due to incorrect transmissions.
- W-410A supports cascade use and independent ID setting. Up to 10pcs W-410A can be used for cascade use. At the same time, it can switch up to 16 radio stations and 16 antennas.
- It supports external control and uses serial TTL level communication. Control protocol is completely public, and users can write control software or use remote control LCD panels to achieve more control methods.
- It is equipped with PC configuration software, and there is a control software demo for users to learn and use.
Notice:
In M-4 mode, the power output can not meet the power detectio requirements of the fast switching mode due to the power change during the tuning, so if you use the tuning antenna, use the standard switching mode. In 4-M mode, it has no effect.
