UG-003 Innovative New Design GPS Antenna


  • RF protection in front-end , protect any kind of receives in the GPS market.
  • Standard WAAS tune from our antennas
  • Short-circuit protection as standard design
  • Wide power supplier voltage from +2.5~12V
  • Narrow band-width<=30 MHz.
  • Cable can be up to >10 meters even for small patch antenna.

UG-003 GPS Antenna is the only innovating design antenna with performance, quality and a Power protection circuit built-in to protect the active LNA’s, and most importantly the host GPS receiver down the connector end from the danger of a SHORT circuit external antenna (Note: GPS receiver front-end can be destroyed or de-graded by an external GPS antenna in an over-load or short conditions. The UG-003 is a low profile GPS active antenna system for the next generation multi-purpose GPS mobile antenna products for Telematics, Fleet Management, Navigations and AVL applications. This small print size of the antenna design does not reflect over-all performance, since the antenna itself needs no ground plane aid to deliver the L1 band small signal carrier that originates from the 24 orbiting USA satellites located thousands of miles over-head and with the ground reception power sensitivity at over -130dB. The UG-003 antenna is also design as a standard power input voltages in range from +2.5Vdc to +12Vdc with reverse polarity shutdown, over-current sense shutdown and an EMC power line suppression. The most important over-all design concept of the UG-003 active antenna is the complete protections of the host sensitive GPS receiver made from any manufacturer that it serve and can also be destroy or de-grade using an improper design antenna.
