Abstract
A portable radio used with this invention has two different types of antenna, such as a monopole antenna and a loop antenna. The diversity reception system continuously selects that one of the antenna which provides the better received signal. Antenna selection is performed such that the received signal level is compared with two or more preset threshold levels, and antennas are switched when and only when the received signal level fails to satisfy certain predetermined conditions.
