Abstract: An arrangement for mounting a directional antenna (10) in an adjustable inclined position to an approximately vertical supporting member (11) comprises a separate upper antenna bracket (12) and a separate lower antenna bracket (12). The two antenna brackets (12) are formed equal to each other and each comprises a first mounting member (13), intended to be mounted to the antenna (10), and a second mounting member (14), intended to be mounted to the supporting member (11). The two mounting members (13, 14) are connected to each other by an intermediate connection (15, 16) which is arranged to permit the two mounting members (13, 14) to be moved a limited distance in an approximately horizontal direction towards or away from each other and to become fixed in adjusted positions relatively to each other.

Abstract: It is presented a service access apparatus arranged to selectively initiate communication with a network node providing a service. The service access apparatus comprises: a data obtainer arranged to obtain a multilevel hierarchical identifier associated with a user of the service access apparatus and when the multilevel hierarchical identifier does not have a lower level first, reversing the multilevel hierarchical identifier; a concatenator arranged to determine a combined domain name; a domain name lookup client arranged to perform a domain name lookup using the combined domain name, and receiving a response of the domain name lookup; and a communication initiator arranged to, when the response comprises a valid resource record for the network node, initiate communication with the network node using a node pointer in the resource record. A corresponding method, computer program and computer program product are also presented.

Abstract: A mast base comprises a rigid body (10) and four supporting legs (15), extending laterally from the body (10) in mutually diverging directions. Each supporting leg (15) comprises an upper arm (17) and a lower arm (18). At its inner end, each arm (17, 18) is pivotally connected to the body (10) for pivoting movement relatively to the body around an appurtenant horizontal pivot axis (x1, x2). At their outer ends, the two arms (17, 18) are pivotally connected to each other. At least one arm (18) has a variable length. The upper arm (17) of each one of two supporting legs (15), which are located at mutually opposite sides of the body (10) and extend in mutually opposite directions therefrom, is pivotally connected to the body (10) by means to two separate pivot joints (19), which are located at a substantial horizontal distance from each other.
