I’d appreciate advice any advice.
After having constant helicopters flying over my house, I wanted to see where they originated and were travelling to that i stumbled on ADSB, I also happen to live in close (<1nm) proximity to London Heathrow
I’ve pulled out my Raspberry pi and bought a cheap RTL device off amazon which came with a cheap whip. I was getting approx. 70 aircraft upto a range of around 100nm.
I’ve since upgraded to the FA pro plus stick and built a spider ground plane antenna where i’m now picking upto 100+ aircraft around 170nm.
A concern i have is with my signal level, i’ve installed graphs1090 and signal looks like below:
(the drop in signal above is due to me tinkering with the gain)
Having an itch to make it betterand wanting to improve is this signal any good?
