The system is currently composed of a "Mini-Whip" antenna, a homebuilt SDR board (as pictured; see here for background) which samples the entire shortwave spectrum and sends all of this via a gigabit ethernet link to a PC, where a special version of the WebSDR server software processes it. The Mini-Whip is based on a design from PA0RDT (google finds it); see some pictures. The active receiving element is about 5 by 10 cm large. Such an antenna only works well with a good grounding; ours is on top of a 20m high building, the upper part of which is all metal.

Lin to the WEB SDR in Nétherlands who use this antenna Mini-Whip
