Mobile GPS Reradiator with LNA

** SPECIAL ** - RRP $169.95

Low-cost GPS Reradiator ideal for handheld GPS receivers, on strength of its un-detachable, built-in GPS antenna design; add value to your Handheld GPS device by enhancing signal reception inside your vehicle or boat.

RA-45 is an integral GPS Reradiator that allows a hand-held GPS Receiver to collect the L1 carrier signal inside buildings, vehicles, trucks or boats, by means of its un-detachable, built-in antenna. Additionally, RA-45 can simply serves as an extension for your antenna. The system integrates our SM-66, a 27db Gain and 50 Ω GPS antenna, into a fully waterproof, low profile and polycarbonate radome enclosure, on which a helical Reradiator rod is mounted. With its built-in voltage regulator, RA-45 derives +12VDC power supply from your car's unregulated DC source. All received signals are reradiated directly with a minimum output power to an attached antenna of yours and locked into an L1 carrier, without the need of pointing the GPS antenna directly to the sky. All you have to is just plug in the power source to your lighter socket, attach the Reradiator and place the RA-45's built-in GPS antenna onto the supplied magnet mount base outside.
