ABSTRACT:
An apparatus for extending the practical lengths over which coaxial cables can be used to transfer signal information from a Global Positioning System (GPS) antenna to a GPS receiver. The apparatus converts the GPS signal frequency of 1.57542 GHz to a frequency low enough to be transferred long distances over coaxial cables without significant signal attenuation and then converts the signal back to the original frequency without the introduction of frequency errors. The invention is not restricted from being used at other frequencies where system design parameters makes it practical.
