SPECIFICATIONS

Amplifiers may be spaced at (8) floor increments when used with model HRT116, HRT112, HRT109 and HRT106 directional couplers. Vertical versions of the taps HRvT106, HRvT112, HRvT109 and HRvT106 are also available. The trunk level is indicated on the left and the tap level output is indicated on the right.

The amplifiers are designed for multiple field powering options. As line amplifiers they pass voltage and 22 kHz tone from RF output to RF input and from RF input to RF output. Each polarity is independently powered. An external power supply from 12 to 20 volts DC can be connected to the DC input connector to power all polarities of the amplifier. DC looping ports allow a single high capacity power supply (model PS201200) to power multiple amplifiers. Each polarity draws 125 ma.
