Production Capabilities

2J Antennas production plant employs skilled staff to produce high-quality antennas delivered worldwide.

To rapidly respond to markets and customers’ needs and carry out the antenna production process from start to finish, 2J Antennas utilizes:

Plastic Injection, Overmolding and Ultrasonic Welding

The company’s plastic injection molding machines run continuously and use only top-grade materials. This ensures that products meet high-quality standards and are delivered on time. In addition, it gives 2J Antennas the flexibility to make overmolded antennas or custom color antenna enclosures.

SMT Pick and Place Lines

2J Antennas uses component placement systems for high-speed, high-capacity and high-precision placement of various electronic components (i.e., surface-mount devices) on a printed circuit board (PCB). This allows flexibility in PCB assembly production.

Cable Processing

The company provides innovative solutions for cable and wire processing. It uses fully automatic wire processing machines for:

  • Cutting
  • Stripping
  • Crimping
  • Tinning
  • Twisting
  • Cable printing


2J Antennas has parts in stock, allowing them to produce all antennas for every order. Its warehouse is organized to support rapid production and flexibility for off-the-shelf antenna customization with no delivery delays. These customizations include:

  • Cable type
  • Cable length

Certification Guidance

2J Antennas offers full wireless device precertification testing with its antennas to ensure compliance with the PTCRB certification program. The testing includes:

  • OTA
  • TRP
  • TIS
  • RSE
  • Cellular device power and sensitivity

Obtaining PTCRB certification for a mobile device ensures compliance with cellular network standards. Without certification, device manufacturers can’t operate with North American cellular carriers.

In addition, the company offers specific absorption rate (SAR) testing. SAR testing ensures a device near a human body under normal working conditions remains within the advised permissible exposure.

Their CTIA-certified 3D antenna measurement systems ensure that devices meet the OTA requirements for network carriers and PTCRB certification.
