- W4245572534 abstract "Abstract Radio antennas that are directive have many advantages over stationary antennas. They can observe in one direction while ignoring much larger signals coming in from the sides. In addition, as transmitting antennas, they can direct a small amount of radiation directly to the proper receiver. Conventional directive antennas use large mirrors for short waves, such as are used in radar. For longerwave antennas, they use reflector and director elements aligned with the antenna. The basic problem with such arrays is that they are mechanically steered, which is slow and difficult to do with large antennas, especially in the presence of wind, ice, or snow." @default.
