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. Frequency range is 5 to 47MHz reverse and 54 to 1000MHz forward. Each drop amplifier features a bypass circuit so in case of a power failure, the amplifier will pass the RF signal through.
