My first collinear antenna

Hi guys.

I'm new at this forum, and new to FR24 to. I've just set up my Raspberry 2 to feed FR24 with data, and with the stock antenna that came with my USB-dongle I get signals from approx. 20 nm. Tonight I built an collinear antenna with five segments, unfortunately I can't test it until tomorrow cause I miss some connectors. Anyway, how much do you think I will increase my coverage with my 5 segment collinear vs my 67 mm stock antenna?

Here is a my antenna assembled
