Portable skid assemblies are shown and disclosed. In some embodiments, the portable skid assemblies include a frame having two or more pockets sized to receive the fork of a forklift, telehandler, or pallet jack. The portable skid assemblies additionally include a support assembly having a base attached to the frame and at least one support member that moves vertically relative to the base between a retracted position suitable for at least one of storage or transport, and an extended position where the skid assembly is configured to communicate wireless signals.

A buried wireless unit measures various soil parameters of surrounding soil and reports them to centralized equipment. In order to provide reliable communication with the centralized equipment, the buried wireless unit may extend a pop-up antenna when transmitting soil parameter data and may subsequently retract the antenna. The wireless unit unwinds and winds a wire, where an electrical cable connects the antenna to a communication module, in order to extend and retract the antenna, respectively. The wireless unit comprises a bendable sleeve enabling the antenna to be flexible so that damage to the wireless unit is avoided if a vehicle (such as a tractor) rolls over the wireless unit. In order to preserve the battery powering the wireless unit, the wireless unit may skip retracting the antenna when the wireless unit determines that charging level of the battery is below a predetermined charging level.
