T-aerial

From Wikipedia, the free encyclopedia

A T-aerial is an antenna (radio) used for VLF, LF, MF and shortwave transmission or reception.

It consists of a horizontal wire suspended between (and insulated from) two radio masts or towers. A vertical wire is connected to the middle of the horizontal wire and hangs down close to the ground, where it is connected to the transmitter or receiver. The two wires form a T shape, hence the name.

Sometimes a group of parallel wires, known as a cage, is used instead of a single wire. This reduces the Q factor of the antenna and broadens the bandwidth over which it will provide good impedance matching.

T-aerials are frequently used as transmitting aerial for long and medium wave broadcasting.
