Test Antenna: An antenna of known performance
characteristics used in determining transmission
characteristics of equipment and associated
propagation paths.
Take-off angle: The angle measured from the Earth’s surface or
horizontal up to the direction of propagation towards the ionosphere.
Three-Element Array: An array with two parasitic elements (reflector and director) and a driven element.
Top-Hat: An antenna that is center-fed and capacitively loaded.
Tower: See Antenna Tower.
Transistor: A minute electronic device that permits a small current
to control the flow of a larger current. [Transistor Manufacturers]
Transmission line: A conductor that transfers radio frequency RF
energy from the transmitter to the antenna or from the antenna to
the receiver.
Transmitter: A piece of equipment that generates and amplifies a
radio frequency, adds intelligence to this signal, and then sends it
out into the air as a radio frequency wave.
Transmitting Antenna: The device used to send the transmitted signal energy into space.
Triatic: A special type of monopole antenna array.
Troposphere: The region of the Earth’s atmosphere from the surface
to a height of about 10 km.
| Towed Dish: Towed antenna, An antenna that is towed behind another vehicle, as shown in the graphic. An antenna that has no fixed location. A similar graphic to the trailer mounted Dish is a Humvee Mounted Dish Antenna, same antenna on a different mount [see Dish Antenna]. A related term is Mobile Antenna. |

Tuning: The process of adjusting a radio circuit so that it resonates at the desired frequency.
Turnstile Antenna: A type of antenna used in vhf communications that is omni-directional and consists of two horizontal half-wave antennas mounted at right angles to each other in the same horizontal plane.
Twin-lead transmission line: A balanced transmission line generally used with balanced antennas.
Two element array: An antenna composed of two element antennas.
