The LNB isn't the only place RF can get into the box. Obviously the plate tells us RF is getting in through the case. Considering the abysmal sheilding I've seen in many STBs this doesn't surprise me in the least. I admit, it's odd that the STB is sensitive to 2.4GHz, but given enough wattage any receive is sensitive. I wonder: is the STB grounded well?
