Matching Units

Antenna matching units are used to improve the reflection coefficient of an antenna at a specific frequency and are mainly used for TV transmissions when a high VSWR produces ’ghost’ images on TV screens. The unit will compensate for a single frequency mismatch of up to 20% reflection coefficient.
