RFI ITG4000 Quadrant Low Profile Patch Antenna

  • True multiband performance 850, 900, 1800 MHz
  • Ideal integrated antenna for ICS, M2M devices
  • Patented mixed polarity design
  • Supplied ready to go with peel and stick mounting.
The Quadrant™ is perhaps the most versatile cellular antenna in the world. It can be used in almost any of the existing cellular systems, will provide superior performance to externally glass mounted antennas and yet can be mounted quickly and easily inside the vehicle with no external parts. Free space field tests show the Quadrant™ exhibiting just over unity gain relative to a quarter wave at GSM900 and WCDMA 800 bands (i.e. 2.5 dBi) and 1.8 dBq of Gain relative to a quarter wave in the GSM1800 MHz and GSM/PCS1900 MHz bands (i.e. 4 dBi). When mounted on a vehicle and tested in full network drive tests (which were performed in an urban environment) it performs even better. This antenna is ideal for installation inside embedded machinery or enclosures where space is a critical restriction and external mounting is not possible. For maximum performance we recommend having the supplied cable reterminated to the shortest length possible to ensure maximum net gain.
