Model LAL204a amplifiers have 20 dB automatic gain input windows to provide a clean fixed output. Model HRT116, HRT112, HRT109 and HRT106 directional couplers tap a portion of the signal to feed distribution nodes. The trunk level is indicated on the left and the tap level output is indicated on the right. Vertical versions of the taps HRvT106, HRvT112, HRvT109 and HRvT106 are also available.
The LAL204a amplifiers are designed for multiple field powering options. As line amplifiers they pass voltage and 22 KHz tone from RF out put to RF input and from RF input to RF output. Each polarity is independently powered. A 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 to power multiple amplifiers. Each polarity draws 125 ma.
