Greatist distance a/c tracked using signal

[marcdeklerk]

hi there!
I would like to know what the Greatist distance an aircraft has been tracked tracked using an antenna! - I have 241nm.. with the supplied whip in a high open area close to my house..

Hello Mark!
I regularly get aircraft squitters more than 320Nm away because of their reflection on the ocean I guess. I have an external antenna+preamp but the site is not particularly optimized.
