I didn't realize ADS-B had that kind of range.

I’m able to track aircraft around 100 miles away using a cheap receiver and a 50’ wire antenna. About $50 total investment. I would guess commercial aircraft must have fairly high watt transmitters.

They have upward-facing transmit antennae for 1090MHz ADS-B/extended-squitter for TCAS reasons.
