NooElec7dBi ADS-B Antenna - 23" Outdoor Fiberglass Antenna with Female N-Connector, 10m RG58 Cable Extension w/Male SMA Connector & Mounting Hardware. Weatherproof. 1090MHz Center Frequency

the connector to the antenna is garbage. It broke off at the base withing 5 minutes of attaching it. Needs a robust connector.

Very good performance at 1090Mhz as advertised. I had hoped to also see decent results at 978Mhz but nosuch luck. VSWR at 1090 = 1.2183:1 VSWR at 978 = Off the charts (ranged out at >20:1).Quality control during packaging is a little lackluster. The first one I received had the mounting hardware for some other antenna in the box. Amazon sent me a replacement that had the correct mounting hardware. Both antennas tested similarly on my LibreVNAI'm using it with a RTL2832U (RTL-SDR) on Raspberry Pi 4 8GB running the adsbexchange raspbian image.

I mounted this on a 6m mast where it has a reasonable 360 degree view. I also didn’t use the supplied cable that comes with it, as I calculated the losses from that cable would be ridiculous. Instead, I opted to install the antenna with a short 30cm RG316 pigtail with suitable connectors to a mast mounted preamp/filter for 1090 MHz directly underneath it un a weatherproof enclosure, then back to the shack via a 12 metre length of RG6 quad shield cable to my ADSB RTL dongle. The result? I started to hear out to 180 nautical miles within 10 minutes of switching on. I can also confirm that a sweep of this antenna with a Nano VNA displays 55 ohms at 1090Mhz and a VSWR of 1:1.13. This thing is legit! If you use the supplied cable to connect the antenna, it will work, but your range will be compromised.

I have been running a virtual radar for a number of weeks with a hand made ground plane type antenna. Thought that I would upgrade the experience by putting a gain antenna in the system. Received the antenna - looks great, everything went together well, but the antenna is completely deaf. No matter how many times I waved it and said virtuous radar expecto, it failed to meet even the basic function of receiving a signal on my SDR.I live on top of a hill with a commanding view of the sky and my $1.50 hand built non-gain antenna can receive signals nearly 100 miles away. This antenna couldn't pick up a 777 within 5 miles of my house.I hope that this is not indicative of the quality of this antenna generally - I live outside the US and returning this product is not an option as I have already paid for shipping and duty. Sad because the item looks great and is well built - just that the innards aren't particularly useful.

The SMA to Type N cable that this comes with is garbage. The coax broke off at the crimp on the bottom of the Type N connector and will need to be replaced before I can test whether the antenna even works.
