Re: Surge Applications
There are no ETSI standards dealing with surge on antenna port. The only body that are working on this item is ITU-T sg5 but are only start to study the problem. THis is normally understand not a immunity test but a survival test (resistibility) and I know to different way: one is inject a High pulse current on the shield of cable with al cable long 10 .50 meters, the other is inject a high voltage pulse on the inner of the cable long some meter.

RE: Surge Applications
Sorry, I forgot to mention that the receiver is also subject to the appropriate ETSI spectrum managment standard. Parameters may include adjacent channel selectivity, blocking and spurious emissions. For example, there are three standards for Short Range Devices: EN300220, EN300330 and EN 300440. There are a large number of other standards that apply to other types of receivers. Good luck!

Receivers are subject to the the requirements of RTTE Directive (see the note in clause 3.1 of EN55022). Your product may also be subject to the appropriate ETSI EMC standard per clause 3.1 of EN55022. If so, the standards would be EN301489-1 plus the particular part that applies to your product. However, if the particular part does not exist, you would use ETS300683. These standards are available for free download at the ETSI web site.
