The ultra-lightweight General Dynamics SATCOM Technologies (formerly VertexRSI) 0.96-meter Quick Deploy Motorized Auto-Acquire (QDMA) Antenna
is designed for worldwide transmit and receive operation in Ku, Ka and X-band.
This portable antenna consists of a segmented composite reflector and motorized positioner mount. This configuration results in an extremely
low-weight and packable antenna product with superior stiffness and high performance under wind loading conditions.
The unique optical shape and accurate reflector surface provide good sidelobe and excellent cross-polarization performance. Repeatability is
maintained with precision registration of the nine-piece reflector segments and RF
components. The antenna can be quickly assembled by one
person in less than ten minutes. The auto-acquire controller
can find the correct satellite and optimize co-pol and crosspol
performance with the push of a button. The antenna
controller can be configured as a multi-functional device
combining several options such as external GUI, monitor and
control, spectrum analyzer and tracking.
The 0.96m QDMA antenna system, including a Stepped Ring
Focus (SRF) feed, is packaged in one or two transit cases
(depending on options ordered). The transit cases, designed
to be checked as airline baggage, feature wheels and suitcase
handles to ease relocation by one person.
