1090Mhz Antenna MCX Plug Connector 2.5dbi gains ADS-B Aerial with Magnet Base RG174 1M+MCX Female to SMA male Adapter Connector

After reading most of the positive review I bought the antenna. Product is as described. But its performance is not as expected. Because I was expecting at least it will increase few nm range to my existing system. I am using home made antenna (uploading image) which is covering 57 nm and tracking around 110 flight on average per day. But this antenna disappointed me: It could track 75 flights and the range was 26 nm max. So I am not using it now. Just using the existing home made one... May be all others positive reviewer's antennas are placed in higher altitude. Mine is at 45 m ASL. I was expected too much as one of the review I read was saying when they got more range and catch more flights immediately when they plugged in. May be its true. But in my case I am not happy.. If some experts reading this please suggest how I can increase or use this antenna more effectively.

I picked this antenna up to use with the blue ADSBexchange dongle and the performance honestly surprised me. For something so small and inexpensive it pulls in aircraft signals extremely well. I have tested a lot of 1090 MHz antennas over the years and this one hangs right with the more expensive options without any drama. The magnet base is strong and works great on anything metal. Stick it to a window frame or a filing cabinet and the signal jumps up instantly. Even indoors the reception holds steady which is rare at this frequency. If you pair it with a good dongle you will have no problem tracking aircraft far outside your immediate area. The MCX connector fits tight and does not wiggle loose which is important when you are running a receiver for days at a time. Once it is connected you can forget about it. If you want an easy and reliable way to get into ADS-B or you need a backup antenna for your setup this one is absolutely worth it. It punches far above its size and price. When paired with the ADSBexchange blue dongle it becomes a tiny powerhouse that just works. I would buy another one without thinking twice.

Had this for some time now and it works great even indoors. It does seem to be targeted for for 1090mhz range. Works great with the rtlsdr dongle. I can track things roughly 150km away which is great for something this small.

I just got this antenna, tested with an analyzer then installed it, and rebooted it. I was getting between 40-50nm of flight positions, now I am getting between 80-100nm. Is that a vast improvement? Depends on how you look at it. This FlightAware server is in a building along with the antenna in a less than desirable location inside. Double the nm distance of visibility is great for me. I did test the antenna on an analyzer before I installed it on the FlightAware USB stick, and it looked slightly better than the stock antenna. I did not expect double the distance of position visibility. The magnet is weak but it does work for indoors. Just stick it on something metal and it will work fine. It didn't want to stand on a wooden desk. LOL. That said, great antenna for the small price you pay to get more positions further away. I hope this helps.

Takes one second to plug in. I use this for a FlightAware PiWare receiver at my condo. The magnetic bottom attaches to my balcony railing. Range is approx 300nm (I’m on the 10th floor) within line of sight.
