Antenna Description

Most Reliable Low Profile Antenna With Exceptional Gain For Challenging Environment

2J7402B-2.4 is a high efficiency, high gain customizable waterproof antenna ideal for external use on vehicles and outdoor assets worldwide. This antenna is a great solution for  2.4 GHz WiFi, BlueTooth, ZigBee, or ISM applications. The 2.4 GHz band uses longer waves, which makes it better suited for longer ranges or transmission through walls and other solid objects. With low return loss and low VSWR, this antenna provides reliable signal transfer even in harsh industrial environments. 2J7402B-2.4 offers an exceptional WiFi peak gain of 3.8dBi for its class of antennas. This antenna caters to 2.4 GHz, WiFi, ZigBee, ISM, Sigfox, RFID , LPWA and LoRa standards delivering exceptional signal quality to mobile devices operating within 2410-2490 MHz frequencies. 

This antenna is linearly polarized with an omnidirectional radiation pattern across the frequency band which ensures constant reception and transmission. With these features, the antenna rejects multipath fading and interference which makes it ideal for moving objects as the signal is not distorted in any direction thus delivering improved signal strength. The antenna features 56.5% efficiency.

Suggested applications include:

  • Automotive
  • Smart home applications
  • Remote monitoring
  • IoT devices 
  • Commercial and residential automation 
  • Handheld devices
  • Mobile and computing devices
