The Toner DDA (Digital Drop Amp) is the newest drop amp model available from Toner. These RF amplifiers feature a precision compact die cast aluminum housing for superior performance and so they can be fitted into the tightest of spaces. Four different amplifier models are available to fit just about any installation requirement. Two with passive reverse (1 and 4 output) and two with active reverse (1 and 4 output). Frequency range is 5 to 47 MHz reverse and 54 to 1000 MHz forward. Each drop amplifier features a bypass circuit so in case of a power failure, the amplifier will pass the RF signal through.
