My reciever was somehow able to MLAT a plane like 278 nautical miles away in the other direction it was facing! Is this real?!

If you recorded the planes ID, you can check where it was at the time

With an average range of about 75nm by the looks. Unlikely
MLAT in itself will need other sync’d feeders seeing it too. So unsure how your station alone would show it out there.
If someone else has their position incorrect and it skewed it maybe…?

You can occasionally get legitimate mlat outliers like this, because all you need to see is a single message from the aircraft to potentially contribute to a result.
that said, there’s not enough info in that cropped screenshot to really verify anything.
receivers with bad positions usually never achieve sync.

Even if MLAT was synced, i totally doubt my reciever can get mode-s from 120NM away… forget about 278NM…

also, it got 2 positions not just 1… indicating the rare possibility of an error

actually, i might have taken a screenshot of that

Most of my pings are regional in my area. Once in a while I’ll get pinged by ANA or JAL or speedbird and AF and Air India on a great-circle route. I try to see how far away from me they are when I’m pinged by copying lat long in the track log to google maps.

That range is amazing! What antenna do you use?

Thanks. I just use the flightaware antenna approximately 34 feet agl with LMR-400 feedline.

Why? That’s not a particularly long range for Mode S / ADS-B. Usually you will be able to receive everything within line of sight of your antenna. I mean, I sometimes get 120NM reflected off a building, let alone direct.

Ducting or reflections are the most likely

Possible but the signal would be out of LOS even through the buildings perspective.

Have a read about ducting

Thank you for that link @geckoVN!
Radio-weather (ie Solar weather) is still something to pay attention to and worth a minute.

We didn’t have satellites in 1943. Other than that, an interesting article

True, but that’s how most people know that style of antenna regardless of what it is pointed at.
“parabolic” doesn’t mean anything to most people.
edit:
Actually I’d argue there was indeed one satellite in 1943.

Agree – the moon.
And I believe Hams do moon bounce.
