Purpose of balun
WebMay 30, 2024 · What is the purpose of a balun? This transformer is known as a balun, and they are in operation in anything from telephone lines to transmitters. Baluns are used both to sort out the flow of AC signals and make the necessary impedance transformation between coaxial cable, which has a low impedance, and balanced loads, which have … WebMay 1, 2024 · The simplest form of choke balun is a coil of coax but a few turns of coax on a large toroid core, such as the DXE-TC31-24-4 in Figure 2 will do a better job over a wider frequency range. Notice that I’ve covered the core with electrical tape to keep the ferrite’s sharp corners from damaging the cable jacket.

Normally, coaxial cable is used to carry video between the camera and the monitor. Substituting networking cable (Cat5 or Cat6) will allow for longer runs at a lower cost. Such video can be carried over long distances, as much as 6,000 ft. Each Cat5 cable contains 8 wires.
Although baluns are designed as magnetic devices – each winding in a balun is an inductor – all transformers made of real materials also have a small capacitance between the primary and secondary windings, as well as between individual loops in any single winding, forming unwanted self-capacitance. The electrical connection of capacitance and inductance leads to a frequency where the electrica…
