This disclosure relates to the use of a mobile device in connection with a balloon network. A disclosed method includes communicating with an antenna structure coupled to the housing of a mobile device. Additionally, the antenna structure may have an omnidirectional radiation pattern when the housing in a first position. The method may also include detecting a reconfiguration the housing of the mobile device. Further, the method also includes communicating with the antenna structure with the reconfigured housing. The antenna structure may have as directional radiation pattern when the housing in a second position. When in the second position the mobile device may be configured to communicate with a balloon network and when the mobile device is in the first position the mobile device may be configured to communicate with a cellular network.
