Methods and devices for securing an antenna or similar device to a structure to inhibit undesirable movement when stowed or folded for travel. A truss having a mount and a plug can be used to secure an antenna to a structure, in particular a rod holder of a boat. A truss can be used to secure the antenna and prevent undesirable contact with other structures. Particular embodiments can be configured to accommodate antennas that, when stowed, are not located near a structure.
