Make in India

Indigenous technology. Sovereign capability.

We build critical RF technology in India. That reduces import dependence, keeps design IP in the country and gives national defence and infrastructure programmes responsive, locally engineered solutions.

  • Indigenous IPDesigns owned and developed in India
  • Local supply chainShorter lead times, easier support
  • Customer-centricClose collaboration with your engineers

Have a specification in hand?

Send us your frequency band, gain, polarisation and platform constraints. Our engineers will respond with a design approach.
