200W Automatic Antenna Switch for Shortwave Radio Receivers - Model W410A

Features

• W-410A is a fully automatic antenna switch designed for the shortwave band with ultra-low insertion loss and excellent isolation.
• Utilizes proven and stable RF Tester technology, offering safe and reliable switching logic. Operates in two modes:
• 4-M Mode: Connects 4 radios to 1 antenna. Automatically detects and switches to the transmitting radio.
• M-4 Mode: Links 4 antennas to 1 radio and switches antennas based on the radio transmission frequency.
• Supports up to 200W RF power continuous operation with built-in 50Ω load resistors for all ports. Non-selected ports are safely switched to a 50Ω load to prevent damage during incorrect transmissions.
• Allows cascading and independent ID settings, supporting up to 10 W-410A units for cascading, enabling the connection of up to 16 radio stations and 16 antennas.
• Compatible with external control via serial TTL level communication. Open control protocol enables custom software or remote control panel integration.
• Comes with PC configuration software and a demo control software for easy learning and use.
