Radio apparatuses for long-range communication of radio-frequency information
Radio apparatuses and methods for MIMO matrix phasing that may be used to toggle and/or weight the amount of MIMO processing based on the detected level of isolation between different polarizations of the system. Also described herein are apparatuses including auto-range and/or auto-scaling of a signal strength indicator to aid in precise alignment of the apparatus. Any of these apparatuses and methods may also include dynamic power boosting that adjusts the power (e.g., power amplifier) for an RF apparatus based on the data rate. These apparatuses may include a housing enclosing the radio device that includes a plurality of pin elements that may act as heat transfer pins and a ground pin for making a ground connection to the post or pole to which the devices is mounted.
