In some embodiments, a first receiver in a plurality of receivers receives a signal via a unicable line from a satellite transmission. The unicable line connects the plurality of receivers to an interface that receives multiple inputs from a satellite reflector dish. The first receiver generates a first unicable message for delivery on the unicable line and detects a characteristic on the unicable line to determine whether a second unicable message from a second receiver in the plurality of receivers is being sent on the unicable line. When the second unicable message is detected, the first receiver delays transmission of the first unicable message by a time period. When the second unicable message is not detected, the first receiver transmits the first unicable message on the unicable line.
