(1) Gain setting of dump1090 above 30 dB greatly reduces performance.
(2) At gain setting of 30 dB, the performance is less than the generic DVB-T, all other parts of system and antenna location being same.
I have to add a Filter. With filter most likely I will be able to increase the dump1090 gain 40+ dB, in which case the performance of Pro Stick will become better than generic DVB-T.
Have to order a Filter. My wallet will be CDN$ 27 lighter!
I have used SMA-male to F-female adapter for Can - Pro Stick combo.
The F- female is up and protruding outside the can. The 1/4 wavelength whip is inserted into it.
The SMA-male is inside the Can pointing down, and the Pro Stick is screwed to it
