2. Balun - Wikipedia

   en.wikipedia.org/wiki/Balun

   An RF choke can be used in place of a balun. If a coil is made using coaxial cable near to the feed point of a balanced antenna, then the RF current that flows on the outer surface of the coaxial cable can be attenuated. One way of doing this would be to pass the cable through a ferrite toroid.

   Female Belling-Lee connector on a television set. The Belling-Lee connector (also type 9,52, but largely only in the context of its specification, IEC 61169, Part 2: Radio-frequency coaxial connector of type 9,52) [1] is commonly used in Europe, parts of Southeast Asia, and Australia, to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal ...

4. Tee connector - Wikipedia

   A tee connector is an electrical connector that connects three cables together. It is usually in the shape of a capital T. It is usually in the shape of a capital T. It is usually used for coax cables and the three connector points can be either female or male gender, and could be different or the same standard, such as F type , BNC or N type .

5. Braid-breaker - Wikipedia

   en.wikipedia.org/wiki/Braid-breaker

   This simple RF choke impedes signals passing on the outside of the braid, which helps to cure television interference. A braid-breaker is a filter that prevents television interference (TVI). In many cases, TVI is caused by a high field strength of a nearby high frequency (HF) transmitter, the aerial down lead plugged into the back of the TV ...

6. Ferrite bead - Wikipedia

   en.wikipedia.org/wiki/Ferrite_bead

   For example, on unbalanced coax transmission lines (such as video cables), the cable is designed to contain the signal, and beads can be used to block stray common mode current from using the cable as an antenna while not interfering with the signal carried inside the cable. In this use, the bead is a simple form of a balun.
