I am not so sure that it is applying to that case, but there are GPS 
antenna cable  extenders which converting down the incoming GPS signal 
to frequencies at which the cable attenuation see here:

I need to send it to someone so that they can check it to see if it works and can track Satellites.  This receiver has the onboard up/down convertor board that changes the receiver input frequency which is set at 4.092 MHz. I don't have the needed down converter at the antenna. I bought this receiver on ebay from someone who told me that he doesn't have the down converter as well and can't figure out how to get it to work at 1575.42 MHz. He also didn't know if this receiver can be setup for a 1575.42 MHz by removing the onboard converter and changing some DIP switches. If one of your members can at least check out the receiver at 4.092 MHz for satellite tracking That would be a big help ...
