Enclosure Kit details:

• Designed for Radio Astronomy and tested with a preproduction LimeSDR board;
• All parts supplied with kit:  no soldering, cutting, filing or special assembly required;
• Sturdy .06” / 1.5 mm custom stainless steel panels with laser cut openings and etched markings;
• Six SMA connectors with coaxial cable leads and u.FL connectors, covering (2) RX, (2) TX, (1)           Optional IO, and (1) Reference Frequency Input;
• Extruded black anodized aluminum split shell case with post-aodization reamed screw holes;
• Passive cooling design resulting in air flow through RF and control panel ventilation holes, adequate for single-channel Receive Operations at typical ambient room temperature;
• Active cooling (using optional fan) to mitigate the effect of  higher ambient temperatures or         simultaneous operation of multiple TX/RX functions;
• GPIO port: D-SUB 15 position connector can be integrated with a forthcoming GPIO Kit;
• External visibility of all activity/status LED sets;
• Design attention to limit corrosion in selection of materials and contact points; and
