Abstract: A small consumer drone is used to measure RF signals, such as within the vicinity of a cell tower. The drone's frame is fitted with an antenna support device which can be in the form of two intersecting arches of dielectric material. An antenna of selected specification is secured to the antenna support. In this way, the antenna support not only provides a secure mounting for the antenna, but also provides protection from objects above the drone.

Abstract: An automatic VNA calibration apparatus is described which requires only a single connection at each of two test ports on a VNA and the pressing of one button. The apparatus comprises a housing for housing electrical components and a multi-throw switch which is controlled by a controller coupled to the housing. The switch is switched between a plurality of positions for coupling to the VNA a series of different calibration and verification components. The components need not be "perfect" standards so long as their values, including the phase shifts which they provide, are accurately measured.
