Flexible and twistable rectangular waveguides are used in a wide variety of satcom, VSAT and telecom applications that carry high frequency radio (microwave communications) signals. Flexible waveguides are manufactured from helically wound silver-plated copper alloy strip material which allows the waveguides to twist and bend in the E and H planes simultaneously. The flexible waveguide core is protected from the environment by a moulded neoprene rubber jacket providing durability and a full axis of motion over the operating temperature range of –20 to +100 degrees Celsius.
