Product information "Common-Mode Choke / RFI-Choke Wideband (2 KW)"
This common-mode choke prevents the shield of the coaxial cable from becoming part of the antenna system and radiating unintentionally. It also serves to match the unbalanced coaxial cable to balanced antennas and can therefore be used as a “1:1” balun.
Built according to the W2DU principle, the Wideband 2 KW choke is extremely broadband and low-loss. A large number of high-permeability ferrite sleeves (28 pieces) are threaded onto high-temperature-resistant PTFE coaxial cable, shrink-wrapped, and fitted with suitable connectors. This makes it easy to integrate into the coaxial feed line.
The Wideband 2 KW common-mode choke is approximately 70 cm long, very broadband and provides about 1500 ohm of common-mode impedance in the frequency range from 160 m to 2 m (1 MHz to 200 MHz). It is weatherproof with shrink wrap and has two high-quality PL259 connectors with PTFE dielectric and gold-plated contacts at the ends. A PL259 connector with PTFE and gold-plated contacts is included.
Important Notice:
When using an End Fed antenna, do not place the common-mode choke directly at the feed point of the antenna! A section of coaxial cable with a length of ≥ λ 0.05 (e.g., about 4.2 m on the 80 m band) should be inserted between the End Fed transformer and the common-mode choke.
