Contact our product experts to discuss your specific system requirements and custom configurations to meet your needs. Most types are optimised to minimise their electro-magnetic shielding. These high-performance components are highly compact, usually mass minimised and ruggedized.
To find out if part number(s) meet regulatory substance or materials compliance (e.g., REACH, RoHS, or any other regulatory requirement) Contact us for compliance verification. Number of coupling paths, type of coupling, and transmission loss may be indicated by the appending of appropriate qualifying symbols.Notice to California Residents: PROPOSITION 65 WARNING Click Here for details. For all other couplers please consult IEEE Std 315-1975. Symbols in this category refer to passive system components used in RF transmission. The most common type of surge protection found in RF applications is the gas-discharge tube lightning arrester. Mode of propagation and other special characteristics, including depicting subtypes, may be indicated by the use of qualifying symbols or characters. Symbols in this category are used to represent stations relating to satellite broadcast and earth communications (satellite ground stations, earth terminals, etc).Ĭommonly used waveguide symbols are found below. Symbols in this category are used to represent conventional ground-based transmission stations, such as telecommunications towers, vehicle mounted radio transmitters, aviation beacons, etc. Other antenna symbols may be used to indicate specific types. The following represent commonly used RF station symbols used on system diagrams, maps, and charts.

The symbol for a wireless link is represented simply by the display of transmitting and receiving antenna symbols, connected by a Radio Link transmission line symbol, which consists of a series of dashes. The symbol below represents the mating of genderless coaxial connectors. The symbol below represents a male and female coaxial connector when mated. Body typically features the active part of the coupling mechanism (e.g. In identification of the male RF connector, the centre contact consists of a pin. Body features a coupling mechanism complementary to the plug. In identification of the female RF connector, the centre contact consists of a receptacle/socket. It is important to note that the contact symbol is not an arrowhead, it is larger and lines are drawn at a 90 degree angle. The following symbols indicate male and female coaxial connectors. RF connector genders are designated either Male (Plug) or Female (Jack) based on the physical characteristics of the connector body and centre contact.
The following denotes a radar antenna rotating four times per minute in azimuth, and reciprocating in elevation 0° to 57° to 0° in one second. It is important to again note that these symbols are not exhaustive. These should only be appended to antenna symbol if essential. Qualifying symbols can be used to indicate a special property of the antenna to indicate polarisation, direction of radiation, or a particular application. Two general antenna symbols are commonly accepted, and can be used interchangeably. Dipole, Loop, and Counterpoise may be indicated using their respective symbols if desired. If required, the general shape of the main lobes may be shown adjacent to the symbol and notes added to show direction and rate of movement (for example, radar rotation). Qualifying symbols may be added to an antenna symbol indicating properties. Types of functions may be indicated by words or abbreviations adjacent to the symbol.

Symbol graphics are provided free for use to all Powertec clients. It is important to note that this article is not exhaustive and contains only commonly used symbols. This page acts as a quick reference to IEEE Std 315-1975 for the production of antenna component diagrams, containing the most commonly used RF symbols.
