AI summary

An RF distribution system distributes a radio frequency (RF) signal to a plurality of receivers. Ports provide RF connectivity from the antennas to the receivers while also providing data connectivity between the receivers. Sensors detect which receivers are connected to the distribution system so that the distribution system can route data from the first detected receiver to the other detected receivers and back to the first detected receiver. The distribution system can dynamically alter the routing if the receiver configuration changes. Consequently, a receiver can send data to other receivers through A-ports and B-ports of a radio distribution system. The A-ports provide RF connectivity to a first antenna while the B-ports provide RF connectivity to a second antenna. Different commands for locking, unlocking, scanning RF spectrum, and configuring can be sent between the receivers via the A-ports and B-ports through the RF distribution system.
