I'll place a preamp in line to see if that increases the SS on the 3805 , maybe my problem is the GPS RX isn't well. Great point.
Note that most GPS engines (including the one in the 3805) report carrier-to-noise ratio (C/N), NOT signal strength. C/N is a function mostly of the antenna location (and, to a lesser extent, the antenna itself). So, while a preamp will raise the signal strength, it will also raise the noise strength, and the C/N -- which is what matters -- will not change much. The cure is to find a better location for your antenna (and possibly get a better antenna, but location is the main thing). If the only better location you have requires a long cable run, a preamp may help to offset cable attenuation.
