In answer to my comment on the lack of an antenna for the Geodesy, Morpheous came up with this great answer, not only does it allow you to stealth install the Geodesy but allows other hand-held GPS devices to function when they can not see the sky.
GPS signals are very low powered, as little as two centimetres of water will stop a GPS signal, this very neat bit of kit allows the Geodesy to be positioned anywhere in the vehicle without the worry of a loss in the signal. This allows you to stealth install the Geodesy or overcome the problems that some vehicles present when it comes to getting a signal.
This kit will also allows other hand-held GPS devices to work, such as using a hand-held GPS unit below deck on a boat.
In the box you get a magnetic mount antenna and mounting plate for permanent fixing.
The complete antenna unit is one piece and powered, consisting of a small square antenna, 2" x 2" x 1" high approx. It mounts almost anywhere, with 10 ft of cable leading to a splitter, one part of the splitter then goes to a cigarette lighter adapter on 3 ft of cable and the other part of the splitter goes to a stick antenna again on 3 ft of cable.
It needs a 12v power supply to work, the cigarette lighter adapter has no electronics in it so you could cut it off and hard wire it if needed.
It works by receiving the signal from the satellites and re-radiating the signal back out at the other end. You have to have the repeater antenna within 25cm of the GPS device, the closer the better. Line of sight is also important, so its best to place the repeater antenna next to the GPS device.
It works a treat and if you want a stealth install of your Geodesy or have a problem with getting a good signal inside your vehicle.
