You can also use a repeater to enable communication between two radios
which cannot communicate directly, perhaps because their users are do not
have line of sight with each other.
The following diagram shows radios A and B and a repeater which are on the
same DMO talkgroup. A and B are in range of the repeater. Because of its
location, the repeater can pass communications between A and B even
though they cannot communicate directly.
