Description
Flexible and twistable rectangular waveguides are used in a wide variety of satcom, VSAT and telecom applications that carry high frequency radio (microwave communication) 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 principal applications are:
• Aid pointing parabolic antennas in line of sight microwave radio links
• Eliminate difficulties caused by misalignment or system variations
• Permit relative movement of equipment due to thermal expansion
• Accommodate moving equipment in radar scanners
• Isolate vibration
