A true braid-beaker breaks the DC path so to block low frequency currents.
It usually consists of two tightly coupled coils which pass the signal, but break the DC path.
Typically they will be a pair of bifilar windings on a toroid, or two loops of coax taped together.
The former can be seen at bottom of https://www.mm0zif.org.uk/training-zone/advanced/filters/
The later is also known as a "Faraday Loop", see https://www.qsl.net/g4wpw/loop.jpg.

Hello fellow Wikipedians,
I have just added archive links to one external link on
Braid-breaker. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{

).

Interference induced into a braid of a coax is not common mode since nothing has been induced into the inner conductor. It is true that the design of braid-breaker choke described here can block common-mode interference in a power cable but this article claims it is about TV interference from the antenna downlead so that is not directly relevant. In any case, a power cable does not have a braid, so there is no braid that needs breaking. Spinning Spark 20:00, 27 October 2021 (UTC)
