The Dielectric Belt Driven Rotator (DBDR) model tower series is a lower-scattering alternative to
conventional metal towers with a roll axis. They are generally used for omni-directional antenna
measurements and are available in two capacity categories: medium and heavy duty.
The primary components include an integrated gearhead roll positioner, mast and a ma-
nual linear offset slide, which allows users to position the AUT’s phase center over the lower
azimuth axis. The base plate of the DBDR assembly provides a convenient interface to
the specifi ed lower positioner. The DBDR series is available in either encoder or synchro
format. Typical axis geometry confi gurations include Roll/AZ.
