Common Antenna
an antenna with auxiliary equipment used for community reception of television and radio signals. A common antenna installation includes the antenna itself, amplifiers, a network of distribution lines, and subscribers’ branch boxes with terminals, designed for connecting a large number of individual receivers (up to several hundred). To improve the reception of television signals common antenna installations use directional yagis and wide-band (multiple-tuned) dipole antennas with reflectors oriented toward the transmitting station. The use of directional antennas and directional branches (in distribution lines) also makes possible the attenuation of multiple reflection images on television screens. A common antenna is usually installed on the roof of a building. One common antenna replaces a large number of individual receiver antennas, improves reception conditions, and does not spoil the exterior of a building. Want to thank TFD for its existence?
