Abstract: An automated transmit combiner monitoring system (100) for an RF radio transmitter system includes a transmitter (101) for providing a primary source of radio frequency (RF) energy and an isolator network (105,107) for isolating the output of the transmitter (101) from secondary sources of RF energy. A transmitter combiner junction (109) is used for enabling the transmitter (101) to provide RF energy to a single antenna (111) while a dummy load (113) is used for loading any unwanted RF energy from the transmitter (101) that is received from the isolator network (103,105). An RF detector (115) is then used for measuring RF energy from the dummy load and an alarm reporting device (119) then monitors the system to provide an alert based on RF energy measured outside a predetermined threshold.
