GPS Antenna sharing
Does anyone have a setup that allows shared use of a GPS Antenna?
We would theoretically like to have three devices have access to a dash mounted GPS antenna.

I am hearing crickets... lots-o-crickets.....
Does anyone have a rig where you have more than one device that needs a GPS antenna at the same time?
PC? handheld GPS unit? nav unit?

I could help you with how to share one GPS signal among multiple mapping software applications on the same computer, but that doesn't sound like what you're looking for.
You have several GPS receiver units, which all accept external antenna inputs, and you want them to share the same antenna, right? Before it reaches the GPS, you still have an analog signal, so I suppose maybe there's some kind of antenna coax-splitter widget out there, but I'd be afraid an N-way splitter would decrease the signal strength N-times.

Geoffff,
You are correct. We have a Garmin NUVI that we will mount to the face of the dash to the right of the driver, ... and we have a Garmin 76CS (i think) handheld that we will likely mount to the pillar to the left of the driver.... and we will have a laptop mounted over/near the doghouse for the passenger navigator to use. We really do not want to have three GPS antennas sitting on the dash, and we do not want to have to swap the antenna lead from unit to unit. I see us most often using the NUVI and PC at the same time.
Any and all suggestions are welcomed.
