Drake DRACOM distribution amplifiers are economically priced, well designed units for indoor use in both residential and commercial buildings where RF signal distribution up to 550 MHz is required. The DDA5542R features a passive return path for signals in the 5 to 36 MHz frequency range. The amplifier incorporates a push-pull, hybrid amplifier. This provides a high quality, low distortion signal for a cable TV drop or the output of a SMATV headend. The DDA5542R also features variable slope compensation. The unit operates from a 24 VDC power supply which is provided. The amplifier circuitry is designed for maximum stability and is housed in a rugged aluminum housing.


  • 42 dB forward gain, adjustable, and a passive return path.

  • Adjustable slope control for maintaining consistent video quality for all channels in the system.

  • Rugged aluminum housing for durability and heat dissipation.

  • Input and Output test connections for convenient monitoring of signal levels.
