The optimal height for 1090 Mhz antenna is 69 mm. you have fully extended the telescopic stock antenna which makes it way too long for 1090 Mhz. Simply collapse it to minimum. It will probably still be somewhat longer than 69 mm, but will perform far better than when fully extended.
Your setup with equipment inside a weatherproof box is cool!
Try not extending the telescopic antena. Check your results. might actually help.
After collapsing the antenna, there was a significant increase in single track messages. I'm still unsure whether this is a good thing or not. However, the Raspi also received more tracks during the early morning hours, which is nice.
Hi David (cecil1829),
Nice setup mate. Can I ask how you inserted the distance column into your feed table on your live map page?
Thanks for any help,
If I remember correctly, by enabling 'site circles' in dump1090's config.js file, the distance column will automatically appear.
