I use this with a SdrPlay RSPdx radio, it works fine when outside. I don't intend to mount it outdoors permanently I don't think it is up to that build quality. If I was I would stick it into a better watertight enclosure and make sure it is out of the summer sun. But for the price it is well built. Inside is one of those PCB 5 x 5 inch patch antennas and a preamp. The preamp runs on 3.3v internally, so 5V power (or 4.7V as the RSPdx puts out) is just fine to power the antenna.
It receives Inmarsat and GPS frequencies inside my house, but for decoding it needs to be outside or at least looking through a window pointed in the right direction. I get much better reception when the antenna is outside.
I would buy this again.
Edit: I have seen some discussion on the web about the coax antenna feed line - i.e. it being very lossy. So I measured it with an expensive VNA. The cable supplied has about 3.8 dB loss at 1550 MHz. To put this in perspective a very expensive, very low loss W.L. Gore type 195 cable (>$300) of the same length measures about 0.9 dB. For my SDR Play RSPdx receiver this extra loss makes no difference, because I have to lower my receivers LNA gain to prevent overload anyway, no matter what cable I use. The cable loss is after the antenna LNA gain, so it doesn't really affect the total system noise figure if at all (3 dB extra loss & 10 dB Assumed LNA gain < 0.5 dB noise figure difference). So my advice is don't fret about it much. It should only be an issue if you are using some SDR Dongle that doesn't have enough gain to begin with, and even then, replacing the cable will have little overall effect. Just try a shorter cable first.

This Antenna Works Pretty Good. The Enclosure Could Be Better.
The antenna works pretty good and all. The case and mount that comes with it could be better. My case that you screw the mount into broke while the antenna was inside and not even being used. The case seems like a soft plastic and breaks pretty easy.But besides the case and mount the antenna does to the job. It needs 5 volts to power the antenna. I also postes two images of the antenna. If I was to mount this antenna outside, I would used another enclosure or put some thing weather proof over the thing.

works better than dual-band GNSS antennas, for PointPerfect corrections (Inmarsat)

No need for two receivers to cover the bands!
