NooElecDual-Band NESDR Nano 3 Premium ADS-B (978MHz UAT & 1090MHz 1090ES) Bundle for Stratux™, Avare, Foreflight, FlightAware & Other Applications. Includes 2 SDRs, 4 Antennas, 5 Adapters.

The included y splitter and an antenna dual tuned for 978/1090 works great. Picking up planes from 45nm away, indoors, in a closet. Using the image from adsb.im these took 10 minutes to set up. I literally spent longer checking the swr of the antenna with a nanovna (I'm an absolute beginner). Don't use a pi, just buy a mini pc with windows 11 and install any Linux distro on it.

Connected these to my PI 4, attached high gain antennas and can watch the local ADSB traffic using Stratux software while at home.Basically experimenting with building an integrated EFB/ADSB in PI based on Lineage OS. So far so good.

Note that the heat sinks included will not fit in the Stratux case. I had to do extensive surgery to get it to fit. Otherwise all works OK. Amazon sent it out with a previously returned defective antenna, but that is not the fault of the kit or kit vendor.

I now have 12 of these deployed in production, to capture anywhere from 140MHz to 900MHz, depending on location, department, ect. They have all been flawless in their quality and thermal design. They get hot, not enough to burn, but so it would be very uncomfortable to keep your hand on them for any amount of time. Every single one I've gotten has worked out of the box, and their tracking and offset has usually been within 50Hz (Yes, Hz, not kHz, not MHz) of where it's tuned too. These are very good for production applications and I highly recommend them if you need a dependable SDR. Capturing at the full 3.2MHz is again no problem at all.

I'm very impressed with these devices!! I am using them with PlanePlotter through the RTL1090 interface and they work great! Easy to set up and had them up and running in minutes. I've just ordered some LNA's and bandpass filters to see just how good they can get but even without them, I am easily tracking targets typically to around 25 nautical mile range and sometimes as far as 64. The amps and filters are an attempt to see if I can get more local targets at low altitude than I presently see but I am guessing there will come some increase in range as well.

The SDRs themselves are great. I'm using them in a Pi Stratux build. The included antennas are junk. The male pins in the SMA connector are easily pushed back into the antenna and won't make contact. With only a few removals they weren't connected at all and ADS-B detection range was predictably terrible.

Bought these for a Stratux build. They haven't given me a bit of trouble. I also appreciate being able to swap out the antennas depending on if I'm airborne or ground based.

Lots of nifty little doo-dads to add to your SDR accessory kit or to go from the SDR and have a feed-throu antenna port in a case. The Y-cable does not make sence, seems like that would be very lossy directly coupling two SDRs together with a common antenna. The cables seem to be decently constructed though. The SDR's them selves are sandwiched into aluminum, they DEFINITELY need the heatsink that is included, perhaps something even more, they get HOT! The antennas are a different story. Not very efficient, not really tuned for ADS-B... not really tuned for anything - they de-tune under a lot of circumstances - antenna angular position, whats placed near, what case is used on the RPi etc. Best is to use a remote USB base and stick the unit upright with the usb connector straight down and antenna straight up with nothing around it. Sensitivity is OK at that point. When using a dedicated, specifically tuned gain antenna outdoors, these little things are sweet for ADS-B
