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.
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 ...
By winding the coax into a coil around some ferite as depicted, these differeneces are eliminated (or at least greatly reduced) by a choking action thus balancing the signal on one end of the device regardless of what is happening on the other.Euc 12:50, 17 June 2012 (UTC) The choke balun does act as a transmission line transformer.
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.
The flange design, inner and outer conductor dimensions are standardized, by EIA, in the RS-225, 50 Ω (ohm), and RS-259, 75 Ω, standards.They are commonly referred to by the inner diameter of the outer conductor in fractional inches.
The connector looks almost identical to a typical BNC connector, but is designed to not mate with BNC jacks. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. The dimensions of the connector are specified in the MIL-STD-348B. MHV connectors can be recognized by the slightly ...
