Kingray MDA22U Low Noise UHF Masthead Distribution TV Amplifier



Kingray MDA22U Low Noise UHF Masthead Distribution TV Amplifier

The Kingray MDA22U is single input low noise UHF TV masthead distribution amplifier designed to amplify the frequency range of 520~694 MHz and for UHF frequencies above 694 MHz filtered, specifically filtering out 4G/LTE & 5G transmissions. Whether the unit is used as a masthead or distribution amplifier, the low noise figure, capacity for multiple channels with low distortion and a high output has proven to be effective in all installations, especially digital problem areas.

The Kingray MDA22 amplifier series is based on a new concept of convergent technology. The characteristics of the integrated chip (IC) selected provide a very low noise figure and an output figure that surpasses most distribution amplifiers hence the name Masthead Distribution Amplifier (MDA).

The Kingray MDA22 can be used in a MATV distribution where there is some distance between the antenna and the headend.

The masthead is powered remotely via either a Kingray PSK06 or PSK06F power supply (sold separately).
