The Tarheel Army Missile Plant was constructed in 1927 as a synthetic fabric rayon manufacturing plant for the A.M. Johnson Rayon Mills, Inc. The company failed in marketing their rayon product to the textile weaving plants in the Burlington vicinity. As a result, the plant was renamed the Carolina Rayon Mills, Inc and a new management was ...
A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.
The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
The Tar Heel Sports Network is a radio network in the United States dedicated to broadcasting live events and programming relating to North Carolina Tar Heels athletics. It is operated by Tar Heel Sports Properties, a property of LEARFIELD, which manages the multimedia rights for the University of North Carolina at Chapel Hill.

Omnidirectional radiation patterns are produced by the simplest practical antennas, monopole and dipole antennas, consisting of one or two straight rod conductors on a common axis. Antenna gain (G) is defined as antenna efficiency (e) multiplied by antenna directivity (D) which is expressed mathematically as: =.
An 1864 letter found in the North Carolina "Tar Heel Collection" in 1991 by North Carolina State Archivist David Olson supports this. A Col. Joseph Engelhard, describing the Battle of Ream's Station in Virginia, wrote: "It was a 'Tar Heel' fight, and ... we got Gen'l Lee to thanking God, which you know means something brilliant." [11] [12]
The horizontal gain continues to increase up to a maximum of about 6.6 dBi at a length of five-eighths wavelength 5 / 8 λ so this is a popular length for ground wave antennas and terrestrial communication antennas, for frequencies where a larger antenna size is feasible. The input impedance drops to about 40 Ohms at that length.
