One unit that has increased in price, but is still likely the least-expensive solution on the market, is the uAvionix skyBeacon. The 978-MHz UAT hardware costs $1,849, but the biggest benefit is the ease of installation. While the installation cost on most systems varies widely for each airplane and, for some, can run into the thousands, the skyBeacon's is very predictable. It simply replaces a wingtip position light with an LED light and requires minimal installation time — the company claims 10 minutes. Experimental aircraft owners can install the product themselves, but certified aircraft require an avionics technician or aircraft mechanic to do the work. The unit provides the required WAAS GPS, ADS-B Out as well as strobe and nav lights. After the installation is complete, the skyBeacon is configured with a mobile Android or iOS device.
