A portable mast capable of supporting a payload that can be fastened to and detached from an unsteady, inclined or irregular surface of attachment. The improvements include a tensioning cable which exerts pressure on the base of the mast in opposition to the surface of attachment, a guide protecting the cable from abrasion, means for adjusting and retaining tension in the cable when the mast is fastened to the surface of attachment, a base capable of housing the fastener to protect the fastener from corrosion and tampering, a base allowing attachment to and pass-through of existing cords crossing the surface of attachment, and a base having resilient compression to conform to an irregular surface of attachment while maintaining pressure between the base and surface of attachment created by tensioning of the cable. Also disclosed is a mast with mechanical means for increasing cable tension in order to secure its tripod base to a surface of attachment. Also disclosed is a mast which can house standardized electronic components required by a variety of payloads, two masts which are capable of communicating with each other to synchronize the movement and operation of payloads, means for passing electronic signals from the surface of attachment through the mast to the payload, and a remote control for electronic communication with a transceiver housed within a mast to control the operations or movement of a payload.
