Laird Connectivity

Laird Connectivity simplifies the rapid integration of wireless technologies with market-leading wireless modules and antennas, integrated sensor and gateway platforms, and customer-specific wireless solutions. Our best-in-class support and comprehensive engineering services help reduce risk and improve time-to-market.



Laird Technologies continues to develop and improve all land mobile radio antenna products. Years of refinement in the mechanical and electrical design of load coil products have resulted in the most technically advanced antennas on the market.

These mobile antennas are designed and built for demanding applications and typically outlast the cars they are mounted on. The antennas are manufactured

in over 100 variations and each model is permanently marked for model and frequency. No ground plane antennas provide flexibility in any mounting

application, while dual and wideband models attain full value out of today’s advanced radios. Please contact Laird Technologies for availability on additional products and mobile applications.


  • Gold plated contact provides the most corrosion resistance and best power transfer over time 

  • ABS material is injection molded directly around the solid brass inserts for a virtually indestructible load coil housing that will not leak or disassemble

  • Stainless steel shock spring or elastomer spring options dampens vibration and will not rust

  • O-ring built into the base provides a weather-tight seal with gold push pin contact for best power transfer over time
