Review on ADSBexchange.com 5.5dBi N-Type Female Antenna (1090/978 MHz) - 24-inch: Boost Your ADS-B Reception! by Don Kishore

Wow! I read that placement is everything. However, I can't help but think that the antenna itself is more important than the toy antenna that came with my NESDR. I went from an average of 4 planes within a 50 mile radius to dozens up to >250 miles. Yes I routed it to the roof using an LMR400 coax and also split the signal to a second orange FA for UAT. 2500 registered positions per day -> more than 25 thousand.
