The MDA1240-E amplifier integrates the advantages of the small sized, high output level MDA product family with
the flexibility of the electronic alignment. The choosable type of the output stage, the between 862 MHz and 1218
MHz switchable bandwidth and the three available versions of diplex filter ensure that the device can fit to any
kind of networks used today. The device is able to forward the remote powering current, this allows to use it
either as a house amplifier or a line amplifier.

• Downstream frequency range up to 1218 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• Electronic configuration interface
• Replaceable diplex filter
• Ingress management
