RFI TLA4100 - 6dBi Transit/Low Profile Mobile Antenna


Key Features


  • Wideband 700 to 5800 MHz performance

  • Low profile, vandal resistant radome

  • Ground dependent/independent capable.




  • The TLA4100 Antenna is designed specifically for rail, light rail and bus applications and other similarly demanding transit or stationary applications

  • With a VSWR less than 2.5:1 covering 698 - 5800 MHz, the TLA4100 operates in all cellular bands globally plus the 2.4 GHz ISM band

  • This antenna also unofficially operates on 2300MHz @ VSWR approximating 1.35:1

  • This antenna can be used in both a ground independent and ground dependent installation - maximum gain is achieved by using up to a 1m^2 metal surface as a ground plane

  • Roof mount multiband "Shark Fin" style antenna designed to operate on all mobile phone and wireless broadband frequencies within the one housing

  • An alternative for use where height is an issue eg. roofs on large motor homes, outdoor data/weather reporting stations, and many more

  • Designed utilising a high impact, UV stabilised low Flame, Smoke and Toxicity (FST) radome, the TLA4100 is IP68 rated to fully protect against the ingress of dust and water

  • This antenna is suitable for installations even in the most demanding of climates.


Designed to meet the following European Traction Industry Standards:


  • NF-F-16-101/102 (materials standard)

  • EN50155 (vibration standard)

  • EN50124-1 (electrical isolation standard)

  • Deutsch Bahn high voltage / current specification
