We manufacture Antennae in the frequency range of M.F., H.F., V.H.F., U.H.F. bands and the antenna supports. Ours is the first company in private sector to start and are pioneers in the field to cater the needs of Defence and Para-military organisations. During the period of more than 3 decades several types of antennae were developed by substituting the products, being imported from outside the country and saved foreign exchange.

The company is professionally managed and equipped with the latest test equipment and recognized by Dept. of Science & Technology, Govt. of India. Every year new products are developed. Some of the products developed in the R&D Section received Import Substitution awards from Govt. and from recognized agencies. For the development of System Engineering Communication Network, we received certificate of appreciation from our Defence customers. One of such appreciation letters received from Indian Navy was, for designing special purpose Antenna System, to establish communication with ‘DAKSHIN GANGOTRI’ to ‘south pole’ and also one from Indian Air Force, for development of H.F. Communication system for low flying Aircraft. The development of Steep Angle radiation H.F. Antenna system for ‘Null Free’ communication for Airforce used in unmanned Airstrips in hill terrains received a merit certificate.

Products developed by the company are processed under strict quality control to ensure reliability, to meet Defence Standards and approvals. Several Antennae are Type Approved and are issued with ‘CAT PART NUMBERS’. Approvals are also received from DOT, Railways and AIR & TV and other Govt. user agencies.

The useful life of Antenna is five to six years and the electrical performance gradually decreases over a period, which is not noticed in regular usage. The impedance characteristics changes slowly and VSWR increases. Hence the company undertakes “Service After Sales” even after the expiry of warranty periods; on reasonable charges. The company also undertakes consultation, field survey to establish line of sight and also supply spares and components, when they are needed
