Antenna Separation: How Close Can You Go?


antenna on car

Hi When building a new robot the mechanical engineers always ask me how close can the different antennas be to each other. It is not uncommon to try squeezing 5+ antennas on a single robot (GPS, GPS2 for heading, RTK, joystick, e-stop, communications, etc..). So what is the proper response? The real answer is that […]

Environmental Sensing and Monitoring


Weather Station

Hi all There are many different types of sensors that can be used for monitoring environmental data. In this post I will focus on natural environmental sensors. By natural I mean I mostly naturally occurring phenomena such as sunlight and temperature. I will mostly ignore things like chemical detection and radiation (the bad kind) detection. […]

Antennas and Amplifiers for Long Distance Wireless Communications


Hi all This is just a quick post on how to increase the range of your wireless communication system. There are several ways to do it and they mostly apply no matter what frequency you are using. We will discuss several ways to do this below. We will also discuss some of the legal limits […]
