As far as range goes on the antenna that you get with the T-ECO, its kinda shit. But about 20 min after hooking it into my rooftop antena ive seen 6 nodes.

I still havent tried driving/biking around town with the smaller antena attached to see if I can find anything.....one of the 6 nodes is brodcasting its location and its in a public park....might start there and see if I can find said node.
