Antenna Balun basics Current balun Unun basics RF baluns are used with many antennas and their feeders to transform a balanced feed or line to an unbalanced one.There are issues when a balanced antenna such as a dipole or similar form of antenna is directly fed with an unbalanced feeder ...
An Unun, short for Unbalanced to Unbalanced, is a type of transformer used in RF antenna systems to match impedance between an unbalanced antenna and an unbalanced transmission line. It is designed to convert the impedance of the antenna to a value that is better suited for the transmission l...

What is the difference between a counterpoise and a radial? Radials hug the ground to help provide alowloss return path for the RF that is soaking into the ground. A counterpoise is used to create an artificial ground when an antenna is elevated. ...
Use Balanced Feeder or Balun The dipole antenna is the balanced antenna. Hence, it is necessary to use a balanced feeder. A balanced feeder consists of two parallel conductors. The currents flowing in both theconductorsare equal in magnitude but opposite directions. Hence, the radiating field fro...
An actual transformer does not use a simple type of structure in which the square magnetic central part is surrounded with coils and gives magnetic coupling. However, it follows the complex design of the core and coil. This involves core-shell, stacked topologies, and lamination. A designer mus...
