Hi-Z Antennas Array Phase Controller Units are the component at the center of a Hi-Z array.
Also known as "relay units", Phase Controllers have the RF phasing electronics and switching devices as well as the connections for the receive antenna feedlines and the main feedline that goes to the system preamp.
Control cable connections are made to these units to steer at the array, with the other end of the control cable connecting to the Shack Switch console.
These Hi-Z Antennas Phase Controllers are made available to be purchased separately as replacements for existing Hi-Z arrays.
