About
The EVR Video Receiver series recovers analog video downlinked from Emhiser’s EVT-series airborne video transmitters, for ground-based display, recording or retransmission at test ranges, UAV ground control stations and reconnaissance receive sites. Catalog entries include EVR-09D2A-00 (single frequency, AC-coupled, 1710.0-1849.5 MHz D2 band), a de-emphasis variant EVR-09D2A-04, RSS-output versions EVR-09D2A-20/-24, and a sub-carrier output option EVR-09D2AA-01. Built in the 09 (9 cubic inch) package, Video Receivers are intended for rack-mount ground stations supporting airborne camera and targeting-pod telemetry downlinks, and are documented in Emhiser’s dedicated Video Receivers catalog PDF.
