21. VOR beacons monitor themselves by having one or more receiving antennas located away from the beacon. 22. BellSouth announced plans to blanket the Southeast, including rural areas and places blocked from receiving antenna service. 23. In a shared system, a receive antenna is usually located at the top of the antenna tower. 24. The frequency-domain cross-correlation algorithm for one specific receive antenna is similar to that in the SISO case 25. These receiving antennas , plus the transmitting antenna, were made of large arrays of dipole wires on wooden frames. 26. It is best for the receiving antenna to match the polarization of the transmitted wave for optimum reception. 27. This means that a receiving antenna " sees " an image of the antenna but with reversed currents. 28. The quality of reception varied greatly, dependent in large part on the location and type of receiving antenna . 29. Line-of-sight propagation means radio waves which travel in a straight line from the transmitting antenna to the receiving antenna . 30. The use of multiple receive antennas ( thus MIMO ) can further improve the reception of STC transmitted signals.
