I am new to this ads-b tracking, and recently got a receiver set up. While waiting for the hardware to get in, I read a bit about making your own antenna to extend the range of the receiver over the standard antenna that ships with the receiver (and which is supposed to be crap).
After a couple tries (one dipole, one colinear coaxial, and another I can’t name), all the antennas, while getting some signal are significantly worse that the original antenna. I am no electric/electronic engineer, so I am probably missing some essential point to antenna design that is so obvious that all the DIY site omit to tell about.
Any help or input on topic would be appreciated.
