How do repeater systems work? | Tait Radio Academy In the 1950s negative impedance gain devices were more popular, and a transistorized version called the E6 repeater was the final major type used in the Bell System before the low cost of digital transmission made all voiceband repeaters obsolete. Repeaters, typically located in a high place such as a mountaintop or tall building, receive a transmission from a radio (in the system) on one frequency and retransmits (or "repeats") on another. They are also used in trunklines that transmit multiple signals using frequency division multiplexing (FDM). 0000115655 00000 n PDF NIOSH Firefighter Radio Communications - CDC Graad 11 Wiskunde Vraestel 2 November 2017, Mobile radios and portables can take advantage of the greater power available in the larger size of the antennas.
