Not on Amazon Mexico either but it just opened July 1.
If you can put it on EBay, Estafeta/Ebay will freight forward direct from US throughout Mexico for a very low transport cost.

I received the FlightAware antenna today and swapped it with my home-brew 9-element collinear. I left everything the same: LMA, power inserter, DC blockers at each end.
It’s been cooking for about 3 hours and my initial opinion is… it’s not as good as the one I took out.
I’ve got Virtual Flight Radar running and I’ll see what the next couple of days brings. But there are several other receivers within 10 miles and I have some history to compare with them.
Where I usually ran about 6 or 7 fewer aircraft tracked in a 24 hour period one other receiver, I’m slowly losing ground with this new antenna. In the past 3 hours I’ve dropped from 8 behind to 11 behind.
Again - it’s early and time will tell. I also have 1090 MHz SAW filter coming in and I’ll see if that helps.
If it doesn’t work out I’ll pull the FlightAware stick and put mine back. I can walk away saying to myself I built a hell of an antenna :mrgreen:
Yeah, my homebrew coco appears to have a bit more gain than the FA antenna too. But mine is physically twice as long so I’d expect 3dB gain just from that… The construction of the FA antenna is certainly a lot better than mine and it probably has a better radiation pattern, though I have no good way of measuring it.
Virtual Radar will help show the receive range and pattern in a few days and that will be the final jury on this. My homebrew stick is also twice the length of the FA but I was expecting the LMA to goose it a bit.
Nice to know I can still build them with stuff found in the garage…
I bought one of these flightaware antennas and I use a male N connector pigtail to mcx connector… I connect my RTL-SDR right at the base of the antenna then I use a quality USB extension cable to the raspberry pi
It works great and there is no loss due to rg6 cable length …
I am a happy camper !!!
Nice! How far is the run from the RTL-SDR to the Pi?
about 4 feet… I know I have a 25 foot USB extension cord just gotta dig it out and try it…
I am using a raspberry pi 2 and a Asus usb n10 mini wifi dongle…
i want to try one or two things …
first put the rtl-sdr unit and the raspberry pi in a sealed waterproof box and just run a usb to mini power cord out to the box …
or
measure the power consumption and use a battery with a solar cell and let the wifi dongle do the heavy lifting back to the router…
I am using a nooelec T2 rtl-sdr with the extruded aluminum case it protects the stick gives it some shielding and helps with heat transfer…
Interesting. Let us know how it turns out.
The amplifier shows 12-18V on its label, however, the power injector is rated at 29V. Won’t this kill the amplifer?
No problem with the voltage. We use them with the amplifier and 12 element colliners and reach out 300+ miles. A nice feature of the dish/directv injectors is the isolation they provide between the antenna/cabling and the receiver. With 35 million satellite customers, they use very conservative designs. Hopefully never needed but nice to have it there.
I just put this antenna up. It replaced the homebrew colinear that I built from the January 2014 QST design. See the antenna design at arrl.org/files/file/QST/This … 013QST.pdf.
The antenna is up only about 10ft behind my house, with a short 6" N to MCX pigtail. The RTL-SDR dongle is mounted on the antenna mast with a 25’ USB extender cable leading to the Pi.
The difference is immediately visible on the local web display. I’m now seeing aircraft sightings 25mi more distant in several directions.
I plan to put this antenna on the roof of my house next week with about 40’ of LMR-400 connecting the antenna to the RTL-SDR. The LMR-400 will have N connectors and I have an N-to-MCX pigtail. No 75 ohm conversions for me. The LMR-400 should have about 1.5 dB of loss, but I’m hoping that the additional height and reduced obstructions will beat that tradeoff.
FA team: thanks for selling these.

Great idea. Please post a follow up to how it turns out.
Maybe I’m doing something wrong but…
Installed this antenna with nothing more than an N to mcx 6" pigtail. Let it run for 24 hrs, messages/planes down 50-75% vs the home made cantenna with a 6" piece of coax and a 6" coax to mcx pigtail. Installed it in the same spot as the cantenna. Max distance was down too. Swapped the cantenna back 8 hrs ago and everything is back to normal.
So this is more than likely going back to amazon.

Wow, that’s weird. I’d give it a few more days. The reason is the first 24-36 hours I saw no change from my home-brew 5-foot collinear to the new stick. Now the numbers are trending up and it’s pulling ahead of the old antenna. I have no idea why the change after that time but I’ll take it.
Message rates are notoriously unpredictable over most timescales (everything from second-by-second through to week-by-week is variable…). So it’s hard to get a proper comparison unless you literally do a side-by-side comparison with two receivers.

Done. Actually I’m comparing to 4 receivers.
See my stats: flightaware.com/adsb/stats/user/bmccaff
After one day, I had 27,795 position reports, up from a previous weekly max of about 18,800 reports, or an increase of 47%. It’s possible my 8-segement colinear was not very well constructed, but I’m impressed with the new antenna. I put another one up on a fence, 42" off the ground running on a standalone instance of dump1090 and it was receiving position reports from similar distances.
I’m looking forward to getting it on the roof in a week or so.

Maybe a bad connector or a bit of insulator braid or what ever shorting and dragging you down.
The new FF is really nice. A bit less range than our 12 segments but not worth fighting over the difference.
Rock solid construction.
I ordered one of the FA antennas. It will be here tomorrow. So we will see if how will it works out for me.
I may have missed in here but can I just get a Male N to F adaptor…so I can already use my MCX to F pigtail and using my coax line then to the from the antenna to the dongle…instead buying another set of different adapters.
