Discone Vs. Homemade Collinear for ADS-B

YouTube user nerdsville shows a signal reception comparison of his discone antenna and his home made 1090 MHz tuned ADS-B collinear antenna in this video. The collinear antenna shows a dramatic improvement over the discone.

ADS-B is a broadcast system which can be used to track aircraft like a radar. More information about rtl-sdr and ADS-B here.

    I honestly cant see how this is right. Ive tried this myself and built a tuned coco antenna corectly built etc etc…same cables, reciever etc and my commercial discone works 10x better. Not only that its broadband so i dont have to change antennas to listen to something other the adsb.
