It has been quite sometime now, (an year to be precise) with the ADSB tracking and all the related stuff. In a place like India where ADSB tracking is not as popular as in the western countries like the US and the Europe, it is always difficult to find people with the know-how on technology like ADSB and even more difficult to implement it by self. But thanks to the great team at FlightAware who have always been at help whenever required and of course to some of the resources on the internet.
Now coming to the point, I have been hosting a flightfeeder at my place for a year, but after a few months I observed that the number of aircrafts tracked and the messages received had fallen down significantly.
Initially I suspected a bad connection and tried troubleshooting with the FA support but unfortunately it did not still work. It was really kind of FA to send me a replacement antenna but even that did not work and the tracking data went further worse. At last, I decided to give a last go before I thought of quitting and surprisingly the coaxial collinear antenna came to rescue with such impressive results. I am satisfied with the coverage and I think anyone facing similar issues must give it a try. It is really cheap and easy to build, but you get impressive results. The one I built could surely have been improvised further but this is all that I could build with my limited knowledge and expertise with antenna. Finally my new antenna is installed and is feeding to Flight Aware.

I would like to thanks @MatthewH2 from FA support for all his troubleshooting help!
