W-410A 200W Automatic Antenna Switch Portable Antenna Switcher Shortwave Radio Receivers Antenna Switch ( Item#: E25901 )

This is a fully automatic antenna switch in the shortwave band with ultra-low insertion loss and perfect isolation.

Features:
It uses stable Radio Frequency detection technology. Its switching logic is safer and reliable. In addition, it has two working modes. In the "4-M" mode, it 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 4pcs antennas to 1 radio, and automatically switch to the antenna according to the radio transmission frequency.
Supports up to 200W Radio Frequency power continuous operation, and has built-in 50Ω load resistors for all ports. In non-selected port status, switching to a 50Ω load resistor eliminates the need for users to worry about damage to the radiostation due to incorrect transmissions.
Supports cascade use and independent IDsetting. Upto 10pcs Antenna Switch can be used for cascade use. At the same time, it can switch upto 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 achieves more control methods.
It is equipped with PCconfiguration software, and there is a control software demo for users to learn and use.
