The ATW251G includes the ATW-R250 receiver and a body-pack transmitter. The ATW-R250 is a non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, which improves operation by providing a ground element in addition to the usual signal element. The ATW-R250 also offers volume control along with AF Peak, RF and Power indicator lights.
