The RF-Connect device turns your Android Tablet into the ultimate pilot tool, delivering ADS-B traffic, GPS position and attitude information – all from a usb receiver that fits in your pocket. But more capability doesn’t mean you have to compromise.

RF-Connect requires no batteries and is powered over usb, easy one-button operation and costs 60% less than comparable ADS-B receivers. It simply works the right way.
