IMPINJ R640 Antenna with Speedway Revolution 4-Port R420 reader - slightly used

Description

IMPINJ R640 Antenna with Speedway Revolution 4-Port R420 reader - used in excellent  working condition.
This is an Impinj xPortal Gateway RFID Reader System.  It is basically an Impinj R420 RFID Reader coupled with integrated beam switching antennas to provide a broad range of coverage. It's like having two circularly polarized better performing Antennas built within.
I've opened the covering so you can see inside and to show the Reader lights up as expected.  It is fully functional and can be Powered Over Ethernet, so I'm not including a Power Supply and Line Cord with it.
Original Part Number is
IPJ-REV-R640-FCC1M1.
Impinj Speedway xPortal Gateway RFID Reader
The Speedway RFID xPortal reader integrates high-performance, Impinj-designed DLPA antenna technology with beam switching and polarization attributes that are dynamically managed by the reader, providing consistent and broad coverage of the read zone. Designed for retail, office, hospital, and other indoor environments, the Speedway xPortal RFID reader is ideal for monitoring tagged items, pallets, equipment, files, or people passing through doorways, hallways, or other zonal coverage areas. The xPortal RFID reader system solves the size and mounting limitations of traditional portals with an attractive, lightweight, and low-profile unit. Measuring approximately 30.5 x 8.75 x 2 in (77.5 x 22.2 x 5 cm) and weighing less than 10 lbs (4.5 kg), its compact form is unobtrusive, streamlined, and ultimately flexible, yet delivers better performance than larger, more costly industrial-scale portals.
