This product is the basis of the desktop shield, which is sufficient for general signal shielding needs. Some customers do not know how to make choices when choosing a shield. The more expensive the better, this is not the case. When choosing a shield, it still needs to be based on the requirements, because if the eight-way signal band mask can satisfy you.
