Q-PAR ANTENNAS USA, LLC

Q-PAR ANTENNAS USA, LLC specializes in the design and manufacturing of advanced RF and microwave antenna systems, precision reflectors, and enclosed positioning hardware for defense and communications applications. Their technical expertise centers on high-performance directional antennas, dual-linearly polarized systems operating at microwave frequencies such as 24 GHz, and engineered aluminum reflectors for signal measurement and testing. The company demonstrates deep proficiency in electromagnetic modeling, antenna enclosure integration, and precision manufacturing for demanding operational environments, with a focus on mission-critical wireless communication components used in radar, surveillance, and signal intelligence platforms. Their ability to deliver custom-engineered antenna subsystems—such as the QLA-360MPS-15 and QSR-340-A-152—indicates strong capabilities in rapid prototyping, RF shielding, and environmental ruggedization for military use. The contractor has consistently delivered specialized hardware to the Department of Defense, supporting programs requiring high-reliability communications, electronic warfare, and test instrumentation. Their work aligns with DoD needs for secure, high-gain, and polarization-controlled antenna solutions across land, air, and maritime platforms. Q-PAR operates primarily within NAICS 334220 and 334290, focusing on the manufacturing of wireless communications equipment and specialized RF components, with additional work in test instrumentation under 334515. This positions them as a niche supplier in the defense electronics supply chain, serving programs that demand tailored antenna and reflector systems not available through commercial off-the-shelf channels. As a small business structured as a 2L entity based in El Cajon, California, Q-PAR ANTENNAS USA, LLC maintains a focused, agile manufacturing footprint. While currently holding no formal government certifications, their proven track record in delivering mission-essential RF hardware to the Department of Defense underscores their reliability as a specialized supplier in the defense electronics sector.
