Repeaters are radio systems that receive a signal and retransmit it, allowing communication over much greater distances than direct radio-to-radio (simplex) operation.
Why repeaters exist
- extend communication range
- overcome terrain obstacles
- support local nets and community activity
How they work
A repeater listens on one frequency and transmits on another. Your radio uses an offset and often a tone to access it.
What affects repeater use
- location and elevation of repeater
- your antenna and power
- terrain and obstacles
When to use repeaters
- longer distance communication
- participating in nets
- mobile operation
