Hi Bob,
If your product utilizes a detachable antenna, a dummy load may replace the antenna per ANSI C63.4 (13.1.3.1). The term “detachable” in this standard is not defined, so is left to interpretation. Technically speaking, if an antenna internally or externally connects to a transmitter via connector, then the antenna could be considered to be detachable. Therefore, the detachable antenna may be replaced with a dummy load during AC conducted emissions testing. However, you know your product’s design and if the RFID antenna is detachable or not. As a suggestion, consult with your test lab to decide if your antenna would be considered to be detachable and if use of a dummy load would be acceptable in your case. IHTH. Please note that the above is my expressed opinion only, except for the standard reference.

The host product complies with Class A limits without RFID module transmitting. RFID has FCC modular approval, but was compliance tested for conducted emissions using a dummy load in place of the antenna. Is it therefore acceptable to also test host product (for FCC Class A compliance) with module transmitting into dummy loads instead of actual antenna? A search of the FCC knowlege database did not turn up any clues. adTHANKSvance Bob Sykes EMC Engineer - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
