ABSTRACT:
A portable communication device which has a horn antenna and a transmitter-receiver and in which the horn antenna can readily be attached to and detached from the transmitter-receiver in a short time. In this portable communication device, a flange on the horn antenna side is connected to a flange on the transmitter-receiver side with four clasps etc. The four clasps etc. are arranged at equal intervals around the outer periphery of the interface of a connecting portion. The clasp comprises a fixing hook portion and a pushing-down portion. The fixed hook portion and the pushing-down portion are fixed to the flanges on the transmitter-receiver side and on the horn antenna side, respectively. The clasps etc. can be operated very easily with a single motion. Therefore, the horn antenna can be attached to and detached from the transmitter-receiver in a short time without a tool. Also, this attaching/detaching operation can reliably be performed in the dark without lighting.
