So I’m brand new at this and just built my PiAware last weekend. I’m using the suggested small magnetic antenna that I bought on Amazon. Since I set it up last weekend I have been receiving pretty good coverage overall – up to 150 miles in certain directions.
I live in west Africa, in a pretty heavily urban environment. My line of sight isn’t the best, and I have the antenna mounted on the outside of a window on the most open-facing side of my apartment, as high as it can be (about 40ft.)
Of course I am like everyone else here trying to maximize my range. So, my question is this – Should I trim the antenna? I have read various places that trimming it to around 67mm will maximize the effectiveness at 1090mhz. Does anyone have any info about this? Is it really worth doing? Do I run the risk of ruining the antenna if I clip it? Finding materials here in west Africa isn’t the easiest task so I don’t want to risk messing anything up.
For reference this is the antenna I am using: https://www.amazon.com/1090Mhz-Antenna-Connector-2-5dbi-Adapter/dp/B013S8B234/ref=sr_1_4?ie=UTF8&qid=1527240652&sr=8-4&keywords=ads-b+antenna
Thanks in advance for your help and support!
