The Haigh-Farr Wraparound™ is a self-contained omnidirectional antenna for cylindrical or conical shaped bodies. A single point feed is used and no external splitters, combiners or cable harnesses are required for installation. The antenna is conformal, and may be mounted flush, or on the exterior of the vehicle. Designs are available from 300 MHz to 13 GHz with typical applications including Flight Termination, GPS, Telemetry, Data Links and Transponder. Multiple antenna elements may be combined within the same physical Wraparound™, providing multi- band capability in a single, compact package. Wraparound™ antennas have been flown on vehicles from subsurface sea to space, including high-mach kinetic kill weapons, high-G projectiles and re-entry vehicles. The Wraparound™ has been qualified for use on several high performance vehicles flown on test and launch ranges throughout the United States and Europe. For high aero-heating applications an ablative heat shield may be added to the antenna for additional thermal protection.

QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.

Toxic gases, such as Silane (SiH4), Nitrogen Trifluoride (NF3), Sulphur Hexafluoride (SF6), Ammonia (NH3), Nitrous Oxide (N2O), etc. must be contained in IMDG certified MEGC tubes for ocean transportation. For high purity gases such as SiH₄, and NF₃, DS Aether CT provides internal-polished tubes to a grade of 3S, 25S, etc. depending on customer's requirements. DS Aether CT’s tubes keep moisture levels below 1 ppm or 3 ppm by a heated vacuuming process so that gas quality can be maintained at high purity level.

We are recognized domestically and internationally for our technology and quality by supplying products manufactured based on our accumulated know-how and excellent technology to power generation equipment companies at home and abroad.

A next-generation Advanced Air Mobility (AAM) aircraft currently under development, designed with a separable upper platform and lower mission module structure. The interchangeable lower modules can be configured for passenger transport, cargo delivery, or reconnaissance missions, offering exceptional operational flexibility across various applications. As a large-scale platform, it embodies the future of modular air mobility, enabling rapid mission conversion, efficient maintenance, and cost-effective operation for both urban and regional air mobility sectors.

Our commercial aerospace AGSE products are relied upon by aviation companies around the world to keep their aircraft serviced and flying. The test and servicing equipment we engineer and distribute are key to the success of commercial aviation.

Surion is evolving into a world-class helicopter The KUH-1, as known as Surion, is the multi-role utility helicopter. The Surion, complete with excellent maneuverability and a world-class hovering capability features cutting-edge avionics system. The copters have been deployed in the Republic of Korea Army(RoKA) for operation since the end of 2012 and carry out missions including troop transport, airfreight, contributing to strengthening military power. KAI continues to expand the scope of operation by development and modification of the military variants such as Amphibious for Marine Corps and MEDEVAC but also para-public uses for National Police Agency, Coast Guard, Firefighting and forest service and so on.
