Printed case from a clever Reddit guy. 2x $1.43 usb extensions. Velcro strap from the bottom on my desk drawer. Yes - those are Legos as spacers........

Antenna might get a bit shorter, but works pretty well. (5 Towers at 1000AGL just north of Minne. and good ES coverage of the big boys upstairs)
Clearly, this design is an acquired taste. Proceed with your giggling - I can handle it! My wife says it needs a sign that says "NOT A BOMB!"

It doesnt have a red flashing light or countdown clock, no bleep bleep sounds so acording to my TV research... Its not a bomb

Pete, when you see the "big boys upstairs", can you also see the little boys below them, when you are close enough?

I am getting good coverage on 978 and 1090. WX data is streaming in, I see the local traffic nearby and airliners up top.

More fun!
Some people ask why a J-Pole.....I Ask, Why NOT!
Easy build and it rocked on 978Mhz! Some scrap plexi, copper tape and a little math! It opens up the possibility of a flexible antenna that could be incorporated into the canopy as well ......
More to come.....

But do you see all the local traffic when the airliners are overhead, or do you only see ADS-B Out equipped local traffic?

I said I had only played with end-fed half wave antennas at HF, but I forgot about my homebrew J-poles for 2m and 440 fast-scan TV.
Great idea! Just hate to see it attached to RG-174 or similar with losses of 1dB/inch  at 900MHz. Well, maybe not quite that bad. Best to mount the receiver right at the antenna and ditch the feedline if you can.
Like I said, awesome geeky thread. Carry on.

ADS-B Out
Hi Leland,
I see all the traffic if it is in the system b/c I am ADS-B out equipped.
So I am seeing 978 out planes, 1090 out planes, and radar targets that are rebroadcast to me as an out equipped plane.
If I have misunderstood your question, let me know.
