Mine arrived today. What a neat device. I'm seeing some aircraft using a Scantenna that's tower mounted. I've got the DPD Productions antenna on the way, but it's going to be a while before it goes up, especially given the wonderful winter we're having here. For the moment the scantenna is enough to get me started.
I was also fortunate enough to have an SMA male to N female jumper, about a foot long, which made it easy to connect the external antenna.
I'm using the FTP feature to upload screenshots to my website. Here's a running example of what I'm seeing. It'll continue to update every minute while I have the system running.
Very very cool device. Lots to learn, but easy to get it going initially.
