High performance, omnidirectional antenna for receiving 1090MHz Mode S and ADS-B data from aircraft. The antenna can be used outdoors, mounted on a mast that is 2.5cm to 4cm in diameter, or installed indoors against a window. When properly installed without obstructions, the antenna can receive ADS-B data from aircraft up to 250mi / 400km away. Mounting bracket and U-bolts included. Compatible with all ADS-B receivers including FlightFeeder, PiAware, Mode S Beast, Radarcape, Kinetic SBS1/SBS3, RTL Dongles, and more.

The outer shell of the antenna is a dark green, rigid plastic topped with a small, black plastic cap. It is not flexible at all.
The mounting hardware that comes with the antenna works well, mounts the antenna firmly to the mast, and is easy to install.
The N connector on the antenna is moisture-resistant but its resistance to weather can be significantly improved by applying silicone grease to the threads, gasket, and connecting surfaces of the connectors, and then wrapping the connection with self-amalgamating tape.
RigExpert scan shows good return loss pretty much right where it's supposed to be. This performs better than my Comet DS150 in this band. Absolutely no performance whatsoever at 978MHz, so anyone wanting to try an use this for UAT as well as ES shouldn't expect to see very much. (This was not advertised as a feature and I didn't expect it - it just would have been nice to have!)
Some comparison snaps since it's been a few days with this new antenna:

Note that I don't have the equipment to properly test the resonance of my homebrew antennas so there's a chance that if you built a perfect antenna that you won't see much improvement.
I have my ADS-B receiver set up in what I call a perfect location - top of a hill with panoramic views in almost all directions.
This antenna is unlikely to improve your receiving range. ADS-B transmissions are very strong, so strong that even a dipole made of two paperclips will generally pick up signals from well over 150 miles away. Where this antenna seems to do well is out of band rejection especially when paired with the filter, which is really important if you are using a RTL dongle and in an area near cellphone towers or other high power transmissions in the 800-1200MHz band.
Instead of an increase in receiving range, you will likely find you get more successfully decoded messages at every range, this is due to the better SNR (Signal to Noise Ratio) meaning a clearer signal and better decoding.
EDIT 7/26/15: Added an amplifier to the antenna and seeing an increase in positions and flights tracked. Used a DC Blocker to be safe, but not positive if it's required. I'll let it run a little longer to rule out normal flight pattern changes before posting a definitive result.
While other antennas may work just as well cut the same wavelength, this for under 50 bucks, is a steal because it includes the mount bracket.
I used an N to F type conversion to SAT TV style coax. RG6.
Wrap it with COAX SEAL to prevent water getting into the connectors. COAX seal is available on Amazon, and local ALTEX style electronics stores.
