RCS Pylons Support structures designed for low RCS measurements Unique ogival shape = extremely low backscatter

A broad selection of pylons, combined with the choice of rotator types allows for a custom fit between pylon and DUT (Device under test). As a result of the unique ogival shape, front and rear sharp edges, and structure surface accuracy, ORBIT/FR pylons demonstrate extremely low backscatter, essential for RCS measurements. Our pylons can be installed on a concrete base, adapter plate, ORBIT/FR positioner, linear slide, elevator or any combination of the above. • RCS measurements • R&D applications • Far-field measurements AZIMUTH ONLY Key Features • Ogive ratio: 1:4 standard, 1:6 and 1:7...

Rotators / azimuth - over - elevation (az/el) "HAT" type rotator with pylon d1 Rotator turntable diameter (flange) d2 Rotator base diameter h| Rotator height t Flange thickness A Rotator (head) B| AZ & EL drive and control system C Tip D Through hole for cables E| Pylon structure F| Support base The “HAT” type pylon rotators are used for heavy duty DUT measurement. This unique hat-shaped rotator is positioned on top of the pylon and provides a mounting interface on its bottom flange to allow the rotator to fit inside the DUT. Fitting the rotator inside the DUT minimizes the rotator's...

Rotators / AZIMUTH ONLY Azimuth only rotator with pylon d1 Rotator turntable diameter Through hole for cables AZ & EL drive and control system Pylon structure Support base EDGE SHARPNESS 0.004-0.008 INCH HEIGHT SURFACE FINISH 63 MICROINCH The Azimuth only pylon rotators are used for an overall small size and light weight DUT in single axis measurement. They incorporate a positioner located in the tip of the pylon. The rotator seamlessly mates with the device under test, preserving the integrity of the DUT’s test evaluation. DUT elevation adjustments can be implemented manually or via a...

Pylon orderinginformation Pylons can be ordered from our selection of standard models or can be customized to suit customer specific requirements. To order a complete pylon assembly follow the example in the table below. Note the series number of the pylon model, the number representing the ogive aspect ratio, and the number of feet for the height of the pylon. Options • Slip rings with up to 30 contacts on the azimuth axis (depends on rotator's size) • Rotary joints for “HAT” type rotators: 12 GHz, 18 GHz, 26 GHz and 40 GHz • Service connector with static cover on top of the "HAT" type...
