Did I ordered this antenna, because the PC I had only meager WLAN reception with constant interruptions and eternal waiting times at the IP assignment by the router (DHCP). The PC is just too far away from the router. First a compliment to Amazon, because the delivery was as always afloat. The antenna can be screwed directly to the PCI-card or on the supplied stand (with 1.3m extension cable, standard connections). In stand strong magnets are integrated. I've chosen the base variant and the part now placed in the windowsill (at the same level of the router of a few rooms away is) and see there full reception. The PC indicates: "Signal Strength: Excellent". Had since then no more demolition and ne reliable wireless connection. So problem solved quickly.
