I am not very sure if dump1090 can merge the feed from 2 dvb-t dongles. This needs input from members who know this for sure.
Directly paralleling two antennas with a Tee is tricky & requires phasing harness.
Using a Satellite TV Splitter 950 -2450 Mhz is another option to combime two antennas. The attenuation to flow of signals between two ports marked TV is very high so two antennas connected to TV or out ports will not suck each other's signal, an all signal flows to in or lnb port.
However the attenuation in the flow from in to out, or lnb to tv, is 3 to 5 dB. If an amlifier is present, it can overcome this loss. This option is worth trying, as it involves cutting the feed cable to CoCo some distance from coco, and inserting the splitter, and connect 2nd antenna to splitter also. Amplifier will have to be located between splitter & power inserter, so that it amplifies the combined signal of two antennas.
If this fails, simply remove splitter, and join CoCo with feed cable directly using a barrel connector, and system will be like before.
