An antenna mast support kit comprising: a generally L-shaped structure having: a tubular leg portion; and an elongate foot portion fixedly attached to the tubular leg portion; a tubular connector member; attachment components useable to releasably secure the tubular connector member to a stationary object; and an anchor plate removably attachable to the tubular connector member, the anchor plate being positionable under a vehicle tire to stably hold the anchor plate against a base surface; the antenna mast support kit comprising a plurality of operating configurations in which an antenna mast is supported within the tubular leg portion comprising: a first operating configuration wherein the tubular connector member is removably attached to the anchor plate and has the elongate foot portion inserted therein and removably attached thereto.

Antenna system includes a base structure and a multiplicity of vertebrae arranged in a stack to define a spine. The spine has an elongated length which extends from a base end to a tip end. A compression applicator is configured to apply an elastic compression force on the stack in a direction along the elongated length from the tip end to the base end. Vertebra interfaces associated with each of the adjacent pairs of the vertebrae are configured to facilitate a variable deviation in an angular alignment of a vertebra axis of each vertebra relative to an adjacent one of the vertebra contained in the stack.

A very low frequency (VLF) antenna includes a metal monopole and a dielectric metamaterial cladding surrounding a periphery of the monopole.

Provided is a reference station device that is capable of high-accuracy positioning whilst maintaining stability, even when configured so as to be portable. This reference station device comprises: communications antennas that conduct wireless communications with a mobile station; a positioning antenna that receives a positioning signal from a positioning satellite; and a control unit that controls the operation of the positioning antenna and the communications antennas. The device comprises: a reference station body to which the control unit and the positioning antenna are mounted; a communications antenna support which supports the communications antennas above the reference station body; and a communications antenna mounting part with which the communications antenna support is detachably mounted to the reference station body.
