Short story : I am wondering how much movement in the antenna is an issue eg. if it moves 0.5m in the wind, is that a problem? What level of movement is acceptable?
N00b here. Started playing with an SDR to listen to airband, had no luck. While getting around to making an antenna for airband, I came across ADS-B and found that interesting, so built a linux VM and have an ADS-B feeder running to various sites.
I’ve just built a spider antenna to try, waiting for some connectors to arrive for me to be able to connect it. I plan to try it in a few locations:
- Inside near a window
- outside, on top of my retaining wall (about 1.5m higher than the window location)
- On my roof, attached to my existing tv antenna.
I live in a valley. I have a few other feeders in a ~30km radius, and they are mostly getting 10,000 - 50,000 positions a day, where I am only getting 1,000. I have a few options:
- Give up - after all, it’s airband I was interested in…but if I can make this work, I’ll stick around with ADS-B running, and probably by a rasberry/orange pi
2.Setup the spider inside and call it good - any data is better than none on the network, right?
- Mount antenna up higher. In which case, for me to get a decent height to try and shoot out of the valley better…I’d need to go 50m to clear the valley, but that isn’t happening. But I might be able to get 2-3 metre above my current tv antenna, if there is value in it…but it would come with some antenna movement, so wondering how big of an issue that is.
I am happy to investigate the option of mounting higher, and I’ll probably test it if nothing else - I might depending on movement, zip tie a pvc pipe for a day and see the results. If it works out, my dad thinks he has a spare extendable steel post antenna that I might see if I can mount (not ideal for my style of house, but should work something out)
