I see ebay has some 10m cables that it says are USB 2.0...interesting. I noticed there are also some repeater units that are a 10m cable with effectively one hub combined that give you 10m, technically that is within the spec.http://www.usb.org/about/faq/ans5
With something like ADS-B we are talking lots of small transmissions that are very short, of a large dynamic range (big difference in signal strengths) from multiple transmitters (aircraft). This means that its impractical to try to automatically adjust the gain of the receiver, if you adjust for a big signal from a local aircraft you would miss the small signal from a far off aircraft...in fact you would never know it is there so could not adjust for it. So an ADS-B receiver needs to handle a wide range of input signals keeping the small signals just about detectable and the large ones below a point where they overload.
