W410A 200W Automatic Antenna Switch Antenna Switcher Suitable for Shortwave Radio Receivers

Features 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 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 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 mod
