Within the R&TTE harmonized standards fa. for SRD's a distinction is made between equipment having
1/ internal and 2/ external or 3/ dedicated antenna's. If your product is tested as an equipment having an external antenna, the test program will be such that the type of antenna should not have impact on the R&TTE properties. Of course, otherwise a HAM product (transceiver) would not be able to be sold in Europe, as the antenna is unspecified. As an antenna is basically a passive element (at least it should), no detoriation of the transmitter properties is to be expected, but for directional properties. Some products won't be allowed with external antenna's, if the requirement is to limit it's geographical range (due to f.a. frequency sharing). Then a dedicated antenna is part of the approval procedure. Of course this IS the always case with internal antenna's. Many SRD devices use dedicated or internal antenna's only. I have to add that the requirement for external/dedicated antenna is most often implemented on regulatory level, and not specifically within the R&TTE. Any permission to use the equipment will be with a prescribed antenna type, and often heigth. Of course, this is country and product type dependent, and subject to frequent changes and (hopefully) harmonization within the EC.

If you change to another type of antenna (passive), will the system still be compliant to the RTTE directive ? Is antenna testing a part of the RTTE testing ?
