PURPOSE: To attain a ground system mobile communication and a satellite system mobile communication with small sized and light weight configuration. CONSTITUTION: A satellite system antenna/high frequency unit 11 is made up of a satellite system antenna of a satellite system mobile communication system and a satellite system high frequency section connecting to the satellite system antenna and an interface being a connector including an interface circuit is projected from the unit 11. A ground system antenna/high frequency unit 12 is made up of a ground system antenna of a ground system mobile communication system and a ground system high frequency section connecting to the ground system antenna and an interface being a connector including an interface circuit is provided projectingly from the unit 12. A repeater 13 has a 1st radio control interface 14 and a 2nd radio control interface 15 and incorporates a circuit by which a signal is sent in two-way between the interfaces 14, 15. |
