DAMS x100 Series

The DAMS x100 Series is our heavy-duty multi-axis antenna measurement system suited for devices up to 150 (68 kg).  It’s perfect for large and unweildy antennas as the positioner is chain and gear driven motor, which enables it to maintain precision positioning even under great weight.

What’s Included?

The standard DAMS x100 package features a 2-axis positioner, our powerful DAMS Antenna Measurement Studio, precision RF cables and rotary joints, all tools and documentation, plus DUT mounting hardware. Everything is backed by 3-year warranty.

Educational discounts are available for students, teachers or staff of universities or technical schools.
