The DTKom Series Amplifiers are professional quality, completely self contained, two way broadband indoor distribution amplifiers designed for multi-channel RF distribution systems where the input source is a cable drop or the output of a MATV/SMATV/CATV headend. The 451280 is a high output level, power doubling amplifier, with an RF bandwidth of 1002 MHz, equipped for 2-way operation with a 42/54 MHz split that can operate in passive or active return configurations.

The 451280 has a user selectable, flat operating, forward gain of 30 dB or 40 dB, with a return gain of 20 dB when in active mode. Lower operating gains can be achieved by adjusting the variable attenuators. The amplifier can be attenuated over a range of 20 dB in the forward path and 20 dB in the return path. Gain and slope controls are located on the front panel for easy set-up and adjustment with the provided tool. Two -20 dB test points are provided to permit testing without interruption of service.
