I hope that the reception problems can be overcome because the fundamental technology and performance are so helpful. You can receive the signals at any altitude, even on the ground before takeoff. The Avidyne EX500 usually has a Nexrad image and most metars for my route before I take off. The EX500 also delivers a great deal of capability for the money. The big screen multifunction display, including the satellite transceiver, costs $8,885. For that you get an excellent moving map, a terrain depiction including obstacles, and data other than weather, such as TFRs. The EX500 with airborne weather radar capability costs $9,995 for basic radars like mine up to $14,995 for the most complex big airplane systems, and it replaces your weather radar display with an improved image, plus all of the other satellite and map data.
