| 11. | It was not until 1987 that WBNR was licensed for 480 watts night time operation with a DA2 antenna pattern.
|
| 12. | The station broadcasts non-directionally during the daytime, and uses a four-tower directional antenna pattern at night.
|
| 13. | In 1957, CBAF 1300 kHz had a radiated power of 5, 000 watts and used a single directional antenna pattern.
|
| 14. | For the realization of this directional antenna pattern two 257 metre ( 835 feet ) tall guyed lattice steel masts are used.
|
| 15. | With the move came the addition of nighttime power, and the elimination of a directional antenna pattern operation during the daytime.
|
| 16. | At night, KTWO uses a directional antenna pattern that pushes most of the station's transmitting power to the west.
|
| 17. | The antenna pattern must be considered because it is costly to change the pattern of a long-wave or medium-wave antenna.
|
| 18. | The power to the difference antenna pattern ( for systems so equipped ) is not adjusted from that of the P1 and P3 pulses.
|
| 19. | Thus as the signal " moves " from one antenna to the next, the distortion in the antenna pattern will increase and then decrease.
|
| 20. | WJMP operated with a maximum power output of 1, 000 watts, using a six-tower, daytime-only directional antenna pattern.
