| description | PURPOSE:To expand a service area by dispersedly arranging an antenna exclusive for receiving and a repeating antenna set provided with a coupler for amplifying a receiving signal and electromagnetically coupling the amplified output with a leakage coaxial line on plural positions of the coaxial line. CONSTITUTION:A repeating antenna 9 is fixed to a leakage coaxial cable 1. A distributed repeating antenna case 1 includes an amplifier 8 (including a solor power supply), a coaxial sleeve antenna 9 and a high frequency connector 11. As shown in the figure, the case 17 is equipped so as to be stuck fast to the cable 1. A messanger wire 15 is a messanger wire for the cable 1 and the case 17 is equipped so as to be externally stuck to the cable 1 and the wire 15 through a nylon belt 16. A coupler 10 can be externally stuck to the cable 1. The repeating antenna set constituted of the antenna 9, the amplifier 8 and the coupler 10 can be used for expanding the service area in a ground section in which a wave propagation state is low. |
