I put DC Filterton feedthrus to power it up. IF i have to run a connunications cable, that gets quite a bit trickier.The Mission Darkness™ RF Shielded Phone & Tablet Locker is a heavy-duty metal cabinet system with 24 individually shielded lockable compartments. It shields portable electronic devices from RF (radio frequency) signals, while securely locked inside. The locker is used for device security in lobbies of military bases, SCIF, intelligence facilities, to eliminate any data .
Copper alloys, mainly brass, bronze, and beryllium alloys, are also used to manufacture RF shielding boxes. Steel – Mild and annealed steels provide low-frequency magnetic shielding. Aluminium – Aluminium is used when the shielding box needs heavier gauge metal and when the RF shielding box needs a metal with high strength-to-weight properties.1.4301 Tinned brass stamping parts Electronic Emi Shielding Rf Shielding Can Metal Cover Boxes The common metal RF shielding materials are copper, aluminum, nickel silver, pre-tin plated steel, and Mu-metal. . Electronic enclosures are box-like structures that are designed to protect, contain, and enclose electronic components such as switches, relays, printed circuit boards (PCB), integrated circuits, power supplies, processors, etc.05 - Radio frequency shielding, also known as RF shielding, is a part that blocks electromagnetic interference (EMI). Simply put, it’s a part made from metal materials that prevent waves from damaging your valuable equipment. Whether in aerospace, healthcare, defense, or communications, choosing the most appropriate material for your application ..75 This discussion covers a subject that I have sought to resolve for a couple of years. A metal box, 2" x 2" x 6" long. Two round 3/8" holes in 1 side 2" appart. (mounting holes) Application is RF. What frequencies up to 40ghz are likely to enter via these holes.
