Matching Ferrite core is an electronic component which has two holes for binding matching coil. Most ferrite core in Sri Lanka is made of ferromagnetic materials. It works as an RF choke when connected to a current which makes it a reliable RF shield as well as a RF decoupling device. Low electrical conductivity in ferrite ring core prevent eddy currents. Small ferrite rod cores or small ferrite cores have low losses when high frequencies are passed which makes it idea for RF transformers such as antennas and tv receivers. Ferrite ring core in Sri Lanka are made using ceramic compounds which has oxygenated transition metals. This gives the ferrite cores its nonconductive ferrimagnetic characteristics. Ferrite core in Sri Lanka mainly used for creating electric transformers (antenna) circuits combined with windings. It is also commonly known as Balun Core, Matching Ferrite Core, ferrite ring core and round ferrite core. In Sri Lanka most ferrite core are used for dc power circuits. Our ferrite e cores and cable ferrite in Sri Lanka have low frequency which makes it perfect for dc power circuits.

Upgrades from 75-Ohm coaxial signal to a 300-Ohm signal. Antenna matching transformer also known as antenna VHF/UHF matching transformer in Sri Lanka is used as a part for for antenna booster circuit. Antenna matching transformer carries solid signal across devices. Our matching transformer for tv antenna is made with weather resistant shielding, if moisture gets in the booster box, it will not effect the transformer. Our antenna transformer is designed to ensure the highest performance and impedance match for areas in sri lanka where the tv signals are severely low. We use high quality materials such as high gage matching coil for solid signal and ur transformer works with most HD UHF VHF Antennas boosters in Sri Lanka. Kumarasinghe Radio Institute manufactured antenna matching transformer or commonly known as uhf vhf transformer in Sri Lanka for over 45 years and has led the antenna industry with durable high performance transformer designs for antenna manufactures. Note that our transformers works as outdoor antenna transformer for any circuits.
