Definition

1. Noun:
   • An antenna for transmitting signals: A transmitting aerial is a specific type of antenna designed primarily for sending out radio or television signals. It is the part of a broadcasting system that converts electrical signals into electromagnetic waves for radiation into space.

Usage Notes

• The term "transmitting aerial" is a technical compound noun. It is more common in British English, where "aerial" is the standard term for "antenna." In American English, "transmitting antenna" is more frequently used.
• It specifically denotes the sending function. A device that only receives signals is typically called a "receiving aerial" or simply an "aerial/antenna." A device that does both is often called a "transceiver aerial" or is described by its context.

Examples

• Noun:
  • The radio station's signal strength depends on the height and power of its transmitting aerial.
  • Engineers installed a new transmitting aerial on the tower to improve the broadcast range of the television channel.

Advanced Usage

• In technical specifications and engineering contexts, the term is used precisely to distinguish from receiving equipment.
  • The design parameters for the transmitting aerial include frequency, gain, and radiation pattern.

Variants and Related Words

• Transmitting antenna: The direct American English equivalent.
• Aerial (noun): The general British English term for any antenna, which can be for transmitting, receiving, or both. The word "aerial" alone does not specify the direction of signal flow.
• Broadcast antenna: A common synonym, emphasizing use for radio or TV broadcasting.
• Radiator: In very technical radio frequency engineering, the part of the antenna that directly emits the waves may be called the radiator.

Synonyms

• Transmitter antenna
• Broadcast tower (when referring to the entire tall structure that supports the aerial)
• Mast (can refer to the supporting structure, but is sometimes used informally for the entire apparatus)

Related Phrases/Compounds

• Satellite transmitting aerial: An aerial designed to send signals to a satellite.
• Directional transmitting aerial: An aerial that focuses its transmitted signal in a specific direction for greater efficiency.
