PDI-860-2W Starburst Series Amplifier
Features Specifications Spec Sheet (PDF)
The model PDI-860-2W is a high performance distribution amplifier designed for use in multi-dwelling units. One of the unique features of this amplifier is that if no AC voltage is available, the unit can be powered by CATV 60-90 volts if present on the cable.

PDI’s dual hybrid power doubling amplifier is housed in a wall mount aluminum case, with large heat sink fins for maximum heat dissipation. The unit is designed to operate up to 860MHz. When fully loaded with 134 forward channels the Starburst Series™ PDI-860-2W has a minimum full gain of +33dB. The -20dB test points are conveniently located externally for testing purposes. The RF input has a surge arrestor for added protection. This high performance amplifier is available with an optional return-path 25dB gain amplifier and an optional AGC circuit for present or future requirements. Forward Gain and Slope controls are located beneath the metal cover to maintain maximum RFI integrity.
