[QUOTE="s-band, post: 973082, member: 407744"] It can escape through any connections, holes below WG cut off and cracks in the case can behave as slot (re-)radiators etc etc. It doesn't surprise me and the levels may be within EMC specs but there's plenty to hear if your wanted signal is -140dBm. Anything before 2011ish wasn't usually tested above 1GHz, now it's 6GHz if if there's a high frequency source inside. As you say, you need a latter day Tempest enclosure [/QUOTE]
