摘要： An extension subordinate machine system enabling high-accuracy correction of the cable loss by adjusting the gain by using the pilot signal and further enabling high-accuracy correction of the loss caused by distribution by a distributor even when a relay device adaptor is connected to the extension subordinate machine through the distributor. With this system, a main machine control section (201) outputs a pilot signal generated by a pilot signal generating section (203) when a switching section (205) sets a measurement mode. A pilot detecting section (215) detects the reception level. A control section (216) detects the pilot signal and sets the attenuation factor according to the reception level of the detected pilot signal. A variable attenuator (206) attenuates the up-link signal and the down-link signal at the set attenuation factor to adjust the gain.

摘要： A road antenna apparatus includes a road antenna 104 which is mounted on a post 103 and at an elevated position on a road R and establishes radio communication with an on-vehicle radio device 102 mounted in a vehicle 101 which is traveling over the road; a controller controls a level of a transmission output signal of the antenna based on a receiving rate of the transmission output signal. A laser-beam emitting device 111 is mounted on the road antenna and radiates a laser beam onto the surface of the road. A laser-beam receiving device mounted on the road receives the laser beam emitted from the laser-beam emitting device. The controller stops the operation of the antenna when the laser-beam receiver device cannot receive the laser beam.

摘要： A road antenna apparatus includes a road antenna 104 which is mounted on a post 103 and at an elevated position on a road R and establishes radio communication with an on-vehicle radio device 102 mounted in a vehicle 101 which is traveling over the road. A receiving rate of the established radio communication is detected. A transmission output is set based on detecting a suitable receiving rate for a desired communications area established between the transmitter and the receiver.
