I'm using an inexpensive antenna and it's not in a great location. It's on a window sill and has only about 90 degrees of unobstructed view all the way to the horizon. The longest detection range is around 150 nm but the average range is 37 nm. Over 95% of the detections are within 50 nm.
Here is the antenna:

Here is the range:

Here is the signal level:

The screen captures are from this afternoon, which is relatively quiet, in terms of aircraft traffic.
According to graphs1090, 2.2% of messages are greater than -3dB of signal strength.
Would it make much difference if I improved the antenna or got an LNA without improving the location?
I was thinking of trying to make a colinear coax antenna using some RG58.
