When the dipole antenna 1 is a ½ wavelength dipole antenna, the total length of the two elements 11 is preferably 2 m or more with respect to the use frequency of the disaster prevention administrative radio of 60 MHz. When the dipole antenna 1 is a ¼ wavelength dipole antenna, the length of one element 11 is preferably about 1 m to the use frequency of disaster prevention administrative radio of 60 MHz, and the end of one element 11 is desirable. A ground conductor may be disposed.

  The element support member 2 supports the element 11 of the dipole antenna 1. In the embodiment, the element support member 2 includes an antenna pole 21 that is tripod-shaped and can be expanded and contracted in the vertical direction, and an antenna mount 22 that projects from the antenna pole 21 in the horizontal direction.

  The door-to-door reception device 4 converts the disaster prevention radio signal received by the element 11 of the dipole antenna 1 into a disaster prevention voice signal and outputs the disaster prevention voice signal. The antenna cable 3 connects the element 11 of the dipole antenna 1 and the door-to-door receiver 4.

  The door-to-door reception device 4 includes a disaster prevention radio signal reception unit 41, a disaster prevention radio signal conversion unit 42, a disaster prevention audio signal recording unit 43, a disaster prevention audio signal output unit 44, and a power supply unit 45.
