Hi mcwito, there are occasionally some returns from Canary Islands, but not any extensive coverage unfortunately (we visit Fuerte and not seen anything from there). If you're reasonably high and have reasonably clear views, you'll get 80 - 100 kms with standard antenna (I get 250 - 275nm which is 440 - 480km, with standard antenna at 200' asl with clear horizon over Atlantic to my west) but if you have any sea views, you'll get considerably further. You need to have a RadarBox connected to your PC to access the network, and it comes with 12 months delayed network. HTH Jon
