Surmedia 20 dB 5G VHF/UHF Home Amplifier with 1 Input and 4 Outputs
Surmedia SMA257 20 dB 5G Home Amplifier with 4 Outputs
The Surmedia SMA257 is an indoor home amplifier designed to amplify and distribute DTT signals to up to four televisions. It features 1 input and 4 outputs, allowing four coaxial lines to be connected to a single aerial feed.
It operates across the VHF/UHF bands from 47 to 694 MHz and provides a maximum gain of 20 dB. It helps compensate for signal losses caused by long runs of 75-ohm coaxial cable and by distributing the signal between several rooms.
The gain adjustment of up to 20 dB allows the output level to be matched to the installation while reducing the risk of signal overload. Its LTE 5G filter with a 694 MHz cut-off helps protect DTT reception against mobile signals outside the television band.
It is suitable for new indoor installations, extensions and upgrades to terrestrial television networks using F-type connectors. It does not distribute the satellite IF band or correct a signal that already reaches the amplifier with poor quality.
