Looks good waiting patiently for mine to get shipped to try it out.
One less adapter to have between the filter and dongle being it is SMA and not MCX.
We are using the same radio chip as the other RTL dongles. You will be able to see both UAT and ADS-B frequencies.
Amplification can cause saturation of the transistors. If you are close to a strong signal it could overload the amplifier or radio.
This isn’t a problem for ADS-B /UAT since the signals are usually very weak.
We have planes flying a thousand feet from the FA antenna with prostick and saw close to saturation levels.
Still nothing to worry about blowing out the amplifier.
The FA filter is definitely good protection from any stray signals that might overload the prostick.
If you are watching a signal NOT on ADS-B / UAT you should be careful of the power level of the input signal.
I don’t think the lack of a TCXO is a major issue for ADS-B. The signal is pretty broad, so as long as the the compensation is set roughly right it shouldn’t make any difference to how many messages you get. It’s much more of an issue for receiving narrow band signals where it can make the difference between receiving the signal or not.
Thanks to everyone for your support – hundreds ordered already today. I hope everyone’s expectations are exceeded! We are testing every unit prior to shipping and very happy with the performance.
Amazon is already showing them starting to ship at the end of the month. Might want to add it’s a SMA connector on Amazon. Didn’t notice that listed anywhere and had to redo the order to add an adaptor.
I am in an area with poor cellular coverage, and testing the Flightaware filter with an older dongle reduced my range significantly. Because of that experience I’d like to connect the FA antenna directly to the ProStick and I am hoping someone can give me a link to the correct cable adapter from Amazon. Looking forward to see how the built-in amp works in this location.
How about putting that Can-ciever in a big inverted soda bottle with the FA filter at the top and a Pi-3 at the bottom with just a power-feed threaded through the screwtop
(cut the bottle where the neck taper starts, insert the gubbins, silicon caulk the cut off neck inside the bottle ans run a bead of the caulk to seal the filter thread and the antenna entry)
Do HOA’s in the USA have regulations about attaching coke bottles to the roof of the house?
Probably, but with the size of the antenna, it could be easily used as a flower pot antenna, or another similar device. Lots of discussion and ideas over on eham.net regarding hoa’s and antennas.
Sort of, but the idea is to hide the antenna so the hoa people can’t see it. Often times they have rules against antennas, but when hidden in something that is allowed, such as a flower pot or something else that is allowed outside the house, people can get away with having the antenna. I don’t live in an hoa community, so i’m really no expert. The spider antenna may be better in the flower pot, hiding a can in a flower might be a bit difficult.
