This is an advanced plan to upgrade the repeater site
to a link system. This plan is suitable for linking three
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 VHF mobile radios and UHF mobile radios.
These VHF and UHF radios work as link radios
between repeater sites.
