![]() For example, although these frequencies travel along “line-of-sight” pathways, radio signals may pass through various non-metallic objects and be picked up through walls or other obstacles.Įven though we can’t see between transmitter and receiver antennas, the radios consider this line-of-sight. However, there are still exceptions to the general rules. Radio waves in these frequencies, unlike AM radio waves, travel in straight lines and, in general, cannot go beyond the horizon or behind solid objects. The frequency range of a repeaters radio available for purchase is typically 150MHz to 900MHz. This lets radio users communicate when obstacles or distance are an issue. ![]() A radio repeater (or a mobile radio repeater) receives a radio signal and retransmits it at a higher power level, allowing it to travel longer distances. All About a Radio RepeaterĪs mentioned above, a radio repeater helps extend the range of a portable or mobile radio system. Repeaters are used in professional, commercial, and government mobile radio systems and amateur radio. What is a two way radio with a repeater service?Ī radio repeater is an electronic device that combines a radio receiver and a radio transmitter to receive a signal and retransmit it over a greater distance, allowing two-way radio communications to go further.Ī repeater at a high elevation can connect two mobile stations that would otherwise be out of each other’s line-of-sight propagation range. What is the Function of a Radio Repeater. ![]()
