Summary: The
RA-45 is a complete GPS Antenna/Re-radiating system to allow a hand-held
GPS Receiver to receive the L1 carrier signal inside the buildings ,
vehicle, trucks or boats, using a hand-held GPS with an un-detachable
built-in antenna or simply just an extension of your Antenna, The system
consist of a high acquisitions SM-66 , 27db Gain, 50 ohm GPS Antenna
into a fully waterproof/low profile polycarbonate radome enclosure and a
helical Re-radiating Antenna rod. The system is powered by the +12VDC
supply through your car unregulated DC source to a voltages regulator
built-in. The received signal is re-radiated with a minimum output power
directly to an attached Antenna to locked into an L1 carrier, with-out
the need to point the GPS antenna directly to the sky. Just plug the
power source to your lighter socket, attach the Re-Radiating antenna and
place the RA-45 GPS Antenna built-in magnet mount base outside. |
