Since a few weeks I’m feeding a couple of sites with ADS-B data.
I use a Raspberry Pi with DVB-T dongle and stock antenna (didn’t even trim the top part off), placed on the second floor behind a window.
Awesome to see aircraft on your own personal radar and enjoying the joy that are subscriptions from the various sites.
However, as most men do; they want to do it better. So I’m think about placing a antenna on the roof, either DIY with some coax-cable or something from Ebay (Ebay seller stanislavpalo130 has an interesting one). But the problem is; I have 2 options to do this:
Put everything on the roof. Raspberry, dongle and antenna. This needs to put in a waterproof box along some DC-DC converter, POE-cables (those cheap ones from Ebay).
Al this connected with one single ethernetcable to inside.
Place a little as possible on the roof. This means only the antenna and dongle. Placing a active USB-cable between dongle and Raspberry Pi.
This would nog only be cheaper but more importantly, much more convenient since you can still reach the Raspberry Pi.
Either cable (ethernet or active USB) needs to be about 10-15 meters in length and feed between a window and window frame. Normal ethernetcable doesn’t fit so I would use flat ethernet cable.
A USB cable will probably fit; if not; I could use a very short length of flat USB-cable.
My questions is; would you guys think this would work? Placing the Raspberry inside, get 10 or 15 meters of active USB-cable outside and connect that to the dongle?
My understanding is the usual (blue/black) dongle won’t work (because of voltage drop) but the tiny small one do (has the SGM2019 voltage regulator).
Because it this works it would be much more practical.
