I would try a smaller antenna !!!!! Larger COCOs , if your maths + construction is NOT ACCURATE will only multiply the errors and produce an antenna with lousy performance.
Larger antennae also drag in more interference, so you maybe overloading the dongle with signals you don't want.
Try a simpler antenna "ABCD567's SPIDER" is a good start... place it in the same place as your COCO, on the same feeder and see how it goes.
For measuring range, I use the RTL1090 software together with "virtual radar" this will map only what you see, and leave it running for 12 hours or so to create a decent map of your coverage.
