A repeater extends communications service area and it
is very useful for two-way communications. Everyone
thinks that the service area should be as wide as
possible such as a cellular phone system. Now the
service area can be extended with Icom repeaters!
This is a basic plan to upgrade the repeater site to a link
system. This plan is suitable for linking two or more
repeater sites. When a subscriber transmits, the
repeater re-transmits a received signal. At the same
time, the received signal is sent to another repeater site,
through a VHF mobile radio. These VHF radios work as
link radios between repeater sites.
