Protótipo para controle de posicionamento de antenas direcionais utilizando dispositivos móveis

Abstract

The objective of this work was the development of a prototype for use with mobile device to control the positioning of a directional antenna of amateur radio to replace the conventional rotators and controls. Due to the high cost of commercially available rotators and the need of using multiple antennas in an amateur radio station, is presented in this project an alternative that can be used to control directional antennas with small size and reduced weight. This monograph presents a low-cost solution, which uses a mobile device with Android operating system and the microcontrolled platform Arduino, to control some stepper motors. A communication module using Bluetooth technology integrates the two subsystems, allowing wireless control of the directional positioning of one or more antennas.
