Thanks to your help I’ve found a cheap offer for the RB Airnav setup, and I purchased the green usb stick with the 1090Mhz outdoor antenna.
The first thing that I noticed is how hot this dongle became.
So I opened it and I put a couple of heatsinks on those two chipset but also the DC regulator runs around 50°C (122°F).
I’m a little bit scared about using that on summer ( here we can get around 40°C (104°F) in the hottest days) so I plan to put It on the north face of the building were is in not affected by sunlight.
The second thing is related to the results that are not much better than the Nooelec Dongle ( which runs cooler thanks to the heatsinks built-in) and the cute general purpose antenna for DVB-T.
Looks like that I can spot only high altitude planes (check the last pic)
Could this be related to the 10Meter coax cable? How much would I gain if I cut this by 2 o 3 meters?
Those are the results that I achieved with my test last day, 6th floor balcony with:
North horizon view
Est Almost Clear, more wall from my building
Ovest Almost Clear
South my wall from my building
11:00 to 14:00 are referred to another location which is clearly worse than the one from 15:20 to 16:40 which is one that I’m talking about
