Abstract

A microwave outdoor radio device includes casing connectable to either the horizontally polarized wave antenna or the vertically polarized wave antenna, coaxial cable terminal that is coupled to casing and that includes connection end connectable to coaxial cable, and coupling means that couples coaxial cable terminal to casing. Coaxial cable terminal is connectable to coaxial cable along central axis of connection end. Coupling means is configured so that connection end can be selectively positioned at two alternative points set at positions line-symmetric to each other about axis line rotated by 45° with respect to central axis.
