The RA-50 is a complete GPS L1 band signal re-radiating unit with dual antennas to re-transmit real-time GPS satellite signal outdoor receptions to an indoor environment. The re-radiating internal antenna allows multi GPS receiver users to perform on-the-fly normal receiver performance within a closed environment, while the main GPS antenna is located on an unmanned outdoor location.
The system kits are designed to operate as whole, it includes a high gain external GPS antenna, precisely calibrated amplifier circuit with Helix type indoor antenna and a power supply regulator built-in.
Excellent for GPS navigation devices installed in cars, buses, trucks, trains, ships and boats etc., especially in urban areas when GPS signals are blocked by high building. You may watch Alvin Magno's review published on Youtube to see how different GPS signals were with and without this re-radiator: https://www.youtube.com/watch?v=8nCLinANsEM.
Applications/Coverage
The re-radiating indoor antenna can support any type of GPS receivers that use the L1 band 1575.42MHz frequency. It can provide good signal reception to a distance up to 2 meters, depending on indoor noise environment. The internal antenna can be used and located in the following to provide good GPS reception environment:
- LABORATORY
- MOBILE HOMES
- VEHICLES
- TRUCKS
- TRAINS
- SHIPS
- SAILING BOATS
- BUSES
