The RK-304 features a wide reradiating range of 30 meters. The RK-304 is an excellent GPS L1 band signal reradiating antenna featuring dual antennas to re-transmit real-time GPS satellite signals from an outdoor to indoor environment. The Xtreme-Radiator system is composed of a highly-sensitive external GPS antenna, a precisely calibrated amplifier circuit with Helix type indoor reradiating antenna, and a built-in power supply regulator. The Helix type indoor re-radiating antenna allows multiple GPS users to share one signal within a closed indoor environment while the main GPS antenna is installed at an outdoor location.

The GPS L1 signal is a 1575.42 MHz frequency, along with a 1.023 Mbps Bi-Phase shift Keying (BPSK) modulated spreading code. The input signal power at the receiving antenna is approximately -130 dBm (spread over 2 MHz). In addition, the unit is designed as plug-n-play hardware and it can be installed either permanently to a secured location or quickly at users' convenience by using either screw mounting or glass suction cup, respectively, for the indoor reradiating helix antenna.

PDF datasheet

• Excellent Re-radiating distance:
  • Reradiating distance of ~30 meters from the reradiating antenna.
• Standard Cable length:
  • 40 meters.
• Highly Integrated System:
  • Designed to operate as a whole, the system kits are composed of a high-gain external GPS antenna, a precisely calibrated amplifier circuit with a Helix type indoor reradiating antenna and a built-in power supply regulator that provides power.
• Efficiency & Convenience:
  • The reradiating antenna transmits real time data throughout the vehicle directly to an unlimited number of users. Multiple GPS receivers or hand-helds can share just one re-radiator to receive timely data.
• Easy-to-Setup:
  • No additional cables are required and no external GPS antennas are needed to be plugged and unplugged when using a GPS receiver inside the vehicle
