Active GPS Booster - September 10th, 2008 by Diplomat Guru
GPS Signal booster
In some modern vehicles certain metalisation processes are used on the glass and front windscreen.
This has the effect of shielding the inside of the vehicle from GPS signals.
This can be very frustrating if your GPS navigator or GPS taxi dispatch pda is mounted inside the vehicle windscreen.
In most cases the advice is to try and connect an external GPS receiver to the device inside the vehicle, this however is not always possible as some devices have a cumbersome socket or no socket at all.
It is also very time consuming having to constantly connect and disconnect the external antenna when removing the GPS device from the vehicle.
An active GPS signal booster fixes this problem by taking the GPS signal from an external antenna and then amplifies it and re-radiates it in the car close to where the GPS device is going to be used.
These devices simply plug into the cigarette socket for power (they can be permanently wired) an external GPS receiver is then connected and mounted on the vehicle. The Device then has a 2M cable with a radiator on the end. Place this radiator wire within 300mm of where the GPS device is mounted and you will suddently see the number of sattelites and the signal strength improve dramatically.
