A receiver assembly for detecting electromagnetic waves or signals over a board frequency range includes a receiver, associated antennas and a carrying case within which the receiver and antennas are contained. The carrying case includes first and second side portions and a carrier board which are hingedly connected together for movement between a condition for storage and a condition for use at which the carrier board is positioned remote of the first case side portion. The antennas are mounted upon the carrier board, and the receiver is mounted within the first side portion of the case so that when the assembly is opened for use, the antennas are supported by the case remote of the receiver. The likelihood of noise production by the receiver circuitry due to the closeness of the antennas to the circuitry and the likelihood that an operator of the receiver will interfere with or distort signals that are transmitted toward the antennas are substantially reduced by the aforementioned support of the antennas remote of the receiver circuitry.
