REQUEST FOR INFORMATION (RFI) Antenna Positioner for Near-Field Range Issued by: Tobyhanna Army Depot (TYAD) Date of Issuance: 2026-04-29 DISCLAIMER: THIS REQUEST FOR INFORMATION IS FOR INFORMATIONAL PURPOSES ONLY. THIS NOTICE DOES NOT CONSTITUTE A SOLICITATION AND SHALL NOT BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT, NOR IS A PROPOSAL REQUESTED TO BE SUBMITTED. RESPONSES IN ANY FORM ARE NOT OFFERS, AND THE GOVERNMENT IS UNDER NO OBLIGATION TO AWARD A CONTRACT AS A RESULT OF THIS ANNOUNCEMENT. NO FUNDS ARE AVAILABLE TO PAY FOR PREPARATION OF RESPONSES TO THIS ANNOUNCEMENT. ANY INFORMATION SUBMITTED BY RESPONDENTS TO THIS TECHNICAL DESCRIPTION IS STRICTLY VOLUNTARY. This Request for Information (RFI) is issued by Tobyhanna Army Depot (TYAD) to solicit information and capabilities from potential sources for the procurement of an antenna positioner designed for use in a near-field antenna test range. The positioner will support precision testing of advanced antenna systems. TYAD has a potential requirement to procure an antenna positioner capable of supporting near-field antenna measurement operations. The positioner should be designed to meet the requirements of precision testing in a near field range environment and include all necessary equipment to enable personnel operation, calibration, and maintenance. I. SCOPE OF INFORMATION REQUESTED We are seeking information on commercially available antenna positioner systems that meet the following requirements. Please provide detailed responses to the following: MECHANICAL REQUIREMENTS Degrees of Freedom (DOF): Provide details for available DOF (e.g., Azimuth, Elevation, Polarization). Accuracy / Precision: Provide details on positioning accuracy, repeatability, and resolution. Load Capacity: Provide the maximum load capacity of the positioner, including overhung moment capacity. Speed: Provide the speed of the positioner's movements in each DOF. Range of Motion (ROM): Provide the positioner's ROM in each DOF. Mounting & Cable Management: Provide details on the mounting interfaces and any integrated cable management or rotary joint features to protect cables during motion. Dimensions: Provide the size characteristics of the equipment and the footprint it will occupy. Alignment: Provide details on the systems used for aligning the positioner. ELECTRICAL AND CONTROL REQUIREMENTS Motor & Feedback: Specify motor types (e.g. servo, stepper, or other) and feedback systems (e.g., encoders). Control Interface: Detail the compatible communication protocols that are supported (e.g., Ethernet, RS-232/RS-485, GPIB, USB). Power: Detail the required power (voltage, amperage, phase). Cybersecurity & OS: Specify the operating system used by the controller and whether the system can operate stand-alone / air-gapped. SOFTWARE & INTEGRATION NSI-MI Compatibility: Detail the capability to integrate within an existing NSI-MI environment, including available drivers or APIs. Automation: Describe support for automated te…
