Shielded room repair is something that we need a lot more of now days. Most of the shielded room problems are simple easy fixes and are quickly found by the trained eye. What the trained eye doesn't catch the test equipment does. Then when you have tested for a number of years you learn where each manufactures room can fail. Every few years its a good Idea to call us to check out your RFI Room. Here is a list of a few things we have found in our general checkup.
loose door hinge
missing di-electric gasket
high pressure helium lines transmitting signal
matted HVAC vents needing cleaned
water damaged panels causing harmonics
aluminum door and window jambs causing corrosion and RFI artifacts
stainless window gaskets needing reset
hat n flat system failure (many causes all fixable)
Most OEM filter panels always need retightened.
loose gaps in foil modular shields
magnet anchor bolts
illegal cryovent systems
grounding Issues (so many Its hard to find them all)
So get a room check up with an RFI test for $2,000.00 Its worth the Image quality increase.
