Thank you @TijnOnlijn for your LABS story about adding an outside antenna to an indoor gateway. Let’s discuss the story in this topic, there are enough antenna experts ( @lex_ph2lb , @jvgenderen ?) in our community to provide feedback to optimize the story (if necessary). https://www.thethingsnetwork…

ah ok, I searched for CXL 900-3LW and found 3 different types … but there are more :slight_smile:

@Epyon , you mentioned using an isolated power supply to complement a grounded antenna cable. Do you have any pointers on where to get those isolated power supplies? I’m having a bit of trouble finding them, at least in versions that are properly sealed off, with a standard 230V connector (as opposed…

would an old pc power supply do? [chintu] Does an ATX power supply have any isolated outputs? switch-mode-power-supply, atx asked by chintu on 07:27AM - 30 Nov 14 UTC

These isolated power supplies are mostly industrial. I always uses DIN rail mounted PSU’s with screw connections, e.g. Phoenix Contact (cheap and reliable). I don’t know if you can find isolated wall wart supplies, which is probably what you are looking for. You need to have some distance between ce…

Many articles books and standards have been written on lightning protection. But even if you do it next to perfect if will still disrupt services.

No it won’t work for our North American frequency of 915 MHZ. This antenna is for the European Lora at 868 MHZ.

during performing reppeatitive tests that I’ve done , the longest communication distance with lora evaluation kit 868 MHZ was 600 meters,how is it possible to make it longer?

Without knowing any details on your tests only generic answers are possible, so here they are: Use a better antenna on the gateway Put the gateway antenna in a better location

I got the sunhans antenna but I don’t have time to test with it. Is anyone interested?

We have that Sunhans antenne on our first floor of our campus and it performs well, as uptil now… I receive Lora beacons transmitted from Mechelen to Leuven, i.e. 30km wit SNR +/- -5 with standard TX power of 14dBm from a pole on 30m AGL. Our gateway is about 20m outdoor. No probs !
