Product information "Common-Mode Choke / RFI-Choke Standard (1 KW) – N-Version"

Common-Mode Choke / RFI-Choke Standard (1 KW) – N-Version

This common-mode choke prevents the shield of the coaxial cable from becoming part of the antenna system and radiating unintentionally. It also helps match unbalanced coaxial feed lines to balanced antennas and can therefore be used as a 1:1 balun.

Built according to the proven W2DU principle, this standard common-mode choke offers broadband performance with very low loss. A series of high-permeability ferrite cores are threaded onto high-temperature-resistant PTFE coaxial cable, shrink-wrapped, and fitted with high-quality N connectors, allowing easy integration into the coaxial feed line.

The choke is approximately 48 cm long and provides around 1000 ohms of common-mode impedance across a wide frequency range from 80 m to 2 m. It is weatherproof, shrink-wrapped, and equipped with N-type connectors featuring PTFE dielectric and gold-plated contacts on both ends.

 Important Installation Note:

When using an end-fed antenna, do not install the common-mode choke directly at the feed point. A section of coaxial cable with a minimum length of λ 0.05 (for example approx. 4.2 m on the 80 m band) should be installed between the end-fed transformer and the choke.

Features

  • Frequency range: 3 MHz to 200 MHz
  • Attenuation: approx. 25 dB – common-mode impedance approx. 1000 Ω
  • Connectors: N-type male to N-type female
  • Power handling: approx. 1000 W
  • Weight: 0.3 kg
  • Length: 48 cm

common mode filter DIY-Bausatz 1 - 30 MHz
1 – 30 MHz Common mode choke DIY kit

1 – 30 MHz Common mode filter with bifilaire windings for optimal attenuation There are many types of common mode chokes available, HF Kits opts for a common mode choke with bifilar windings for optimal filtering. This 1 – 30 MHz common mode current filter is optimized for the 80 and 160 meter band. In this case a FT240-31 toroidal core with optimal performance for the lower frequency range is used. The 1 – 30 MHz common mode choke performs very well on the entire HF spectrum. The attenuation is therefore around 30 dB across the entire HF frequency spectrum. This filter is therefore a real all-rounder for amateurs who want to work from 160 meters to 10 meters. Even people who deal with LPAM (Medium Wave) can use this filter. The main reason for using a common mode choke is to ensure that the coax cable’s shield does not become part of the antenna system and will radiate unintentionally. This has all sorts of nasty effects, think of: interference issues, disrupted radiation pattern of the antenna and a higher noise level. This last point is because not only does the coax cable’s shield radiate when you transmit, but the shield also works as a receiving antenna. Because the coax cable often makes a considerable trip within the house, close to interference sources (mains, PLC etc…) It is useful to eliminate these sources of interference. Any way, Good reason to use a common mode choke. The effect of this common mode choke with bifilar windings is difficult to predict. This depends on local circumstances. Think of: antenna type, antenna placement, type of feed line, feed line placement and especially local sources of interference. There are manufacturers that promise in advance a significant drop in interference, however this is not real. There are cases where the noise level decreases by two to three S points, but also cases where the filter has almost no effect.
