Original short-wave choke magnetic ring, for 1.8-54MHz HF short-wave radio, anti-interference 1:1 current type Barron

Short-wave radio choke magnetic ring, choke coil, common-mode current suppression magnetic ring, 

1.8-54MHz HF shortwave radio anti-interference 1:1 current type Barron. 

High-quality magnetic ring production

Adopt high-quality nickel-zinc magnetic ring, 

accept the suggestion of Youtai in the early stage, 

This time, it is made of high-quality-3 ultra-flexure feeder winding, 

and both joints are made of pure copper welding and assembly joints. 

How to use the choke circle: 

1. Be sure to connect the choke directly to the output of the short-wave radio, 

The M male at the end of all the choke circles.

2. The other end of the choke is directly connected to the feeder, 

If there is a celestial tone, connect the celestial tone and then connect the feeder. 

3. The function of the choke is to eliminate the interference caused by the common mode current. Because the whole sky feed system we use, such as antenna, feeder, barron, etc., will not be the standard balance system, Therefore, an electric current will be formed in the shielded metal layer of the feeder, which is also an interference signal. And with the increase of the transmission power, there will be all kinds of strange problems when playing FT8. The use of chokes to suppress or eliminate common mode current is a mature technology used by almost all equipment. For example, the EMI filter used in the switching power supply.
