Check out the RFI ITG4000 Quadrant Multiband Cellular Antenna's Key Features
(RFI ITG4000)

  • Genuine Australian RFI 1 Year Warranty
  • Peace of Mind Purchase Guarantee (bottom of page)
  • 806-890MHz/1710-1990MHz
  • Truly global cellular coverage- One antenna suits all systems
  • Superb performance Patented mixed polarity design
  • Completely internal installation
  • Supplied with peel and stick mounting and pre-terminated, fully shielded low loss coaxial cable


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.

The RFI Quadrant™ uses the same stripline fed slot radiator technology with patch circuits used to introduce multi band performance. Being slightly larger than the dual band Duet™, the Quadrant™ has been configured to suit not only GSM900 and GSM1800 systems but also covers AMPS, TDMA and CDMA 800 systems. It also covers the GSM1900 and PCS1900 bands. This enables the Quadrant to be used in more than nine out of ten cellular systems anywhere on the globe.

Take the RFI Quadrant to almost anywhere in the world, and the antenna can be installed quickly, easily and yet deliver incredible performance. With a unique mix of vertical and horizontal polarisation (as is also shown by the cell sites themselves), the Quadrant™ will work especially well in urban and suburban areas. It even out-performs its sister, the Duet™, because of the very slightly larger footprint.

Free space field tests show the RFI Quadrant™ exhibiting just over unity gain relative to a quarter wave at GSM900 and AMPS/TDMA/CDMA 800 Bands (i.e. 2.5 dBi) and 1.8 dB of Gain relative to a quarter wave in the GSM1800 MHz and GSM/PCS1900 MHz bands (i.e. 4dBi). When mounted on a vehicle and tested in full network drive tests (which were performed in an urban environment) it performs even better.

Mounted on a vehicle screen, the RFI Quadrant™ is rated at –1dB over a 3 wave, but this is some 5-6 dB BETTER than even the best externally mounted glass mount antennas and more than 12dB better than using a portable phone in the car without an external antenna!

The RFI Quadrant is truly a breakthrough. There is no performance trade-off. One antenna provides global cellular coverage (ideal for vehicle manufacturers or hands-free kit manufacturers) with a single item. No installation mistakes, with one antenna for every job, and a simple installation with no external parts to be fitted.

Supplied complete with mounting instructions and a preterminated low loss, fully shielded coaxial cable, the RFI Quadrant can help reduce inventories, reduce installation costs, boost air time and deliver superior customer satisfaction in just about every cellular system in the world.
