Answer:
Types of functions may be indicated by words or abbreviations adjacent to the symbol. Qualifying symbols may be added to an antenna symbol indicating properties. 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).
General Antenna Symbols
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.
