Shortwave Choke Magnetic Ring 1.8-54MHz Shortwave Radio, Anti-Interference 1:1 Current-Type Balun 200W

Shortwave Choke Magnetic Ring 1.8-54MHz Shortwave Radio, Anti-Interference 1:1 Current-Type Balun 200W Popis

1. Always connect the choke directly to the shortwave radio output. All chokes should have a male (M) end.
2. Connect the other end of the choke directly to the feeder. If an antenna tuner is used, connect it before connecting to the feeder.
Features:
The purpose of the choke is to eliminate interference from common-mode current. Because the antenna, feeder, balun, and other components in our antenna and feeder system are not standard balanced systems, current will form in the feeder's shielding layer. This current is the interference signal, and it increases with increasing transmit power. This can lead to various strange problems when using FT8. Using chokes to suppress or eliminate common-mode current is a mature technology used in almost all equipment, such as EMI filters used in switching power supplies.
