- W2217253992 abstract "This project is the design of an antenna-coupling unit (ACU) that will operate with the Texas Instruments LORAN-C receiver and a 28-inch antenna. The height of the antenna used at the present is eight feet. Since the application of LORAN-C positioning is being expanded to vehicular location, an eight-foot antenna is not practical. The shorter antenna is necessary to prohibit striking trees, overpasses, etc. The newly designed ACU has more voltage gain to compensate for the attenuation of the incoming signal due to the shortening of the antenna. It also has a bandpass of 90 KHz-IIO KHz with the center frequency being 100 KHz, the carrier frequency of LORAN-C, and provides matching between the receiver and the antenna. The new ACU has comparable performance when compared with the TI ACU, but the signal-to-noise ratio is not high enough in many cases. This occurs because low-noise transistors were not used." @default.
