The MHW25FS is a VHF/UHF TV masthead amplifier, enclosed in a fully shield die-cast housing, with the capability of amplify signals either from combined or separate VHF and UHF antennas.

The Kingray Masthead range includes both wideband and VHF or UHF only models & with UHF frequencies above 694 MHz filtered, 4G/LTE transmissions are filtered out. In addition to the 4G/LTE filtering, most wideband models include low band filtering to eliminate all services below 174 MHz. This amplifier also has the ability to allow FM radio signals to be passed through.

The masthead is powered remotely via a Kingray PSK06 or PSK08 series power supply (sold separately).
