An antenna feed assembly is provided which includes at least two elongate feed chains lying adjacent one another. A request for a network address is received from a client. Such a configuration allows an effective tuning of the frequency bands of the antenna, such that with the same overall antenna size, said antenna can be effectively tuned simultaneously to some specific services, such as for instance the five frequency bands that cover the services AMPS, GSM900, GSM1800, PCS1900, UMTS, Bluetooth, IEEE802.
