<P>PROBLEM TO BE SOLVED: To promptly detect a change of installation environments for a retransmission apparatus. <P>SOLUTION: A high-frequency signal received by a receiving antenna 2 which is installed in a support post 10 is amplified by a head amplifier 4 installed in the support post 10 and an MCPA 6 installed in a support post 24 to be transmitted from a transmission antenna 8 installed in the support post 24. The head amplifier 4 and the MCPA 6 are provided with inclination sensors 14, 30. When the inclination sensors 14, 30 detect an inclination different from a predetermined standard inclination, a transmitter 36 transmits a notification signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
