wow, that’s a lot of satellites. This would be interesting with the new T-Echo board which supports multiple GNSS constellations.
Well, look what I found. I just ordered 3 of them. I’ll let everyone know how they work out.
This could be a performance game changer and up the cool factor of all the cases.
Quad Helix Antennas have arrived. I hope to do some testing on the weekend.
Quad helix antenna seems to work at least as well as the patch antenna on the T-Echo. This was just a quick test indoors. Both picked up 6 satellites.
Interesting test… Not what I was expecting, but it could be too early to draw any conclusions.

Aliexpress doesn’t have that antenna anymore. Searching online, different ebay listings for Beitian BT-1634 also come back as unavailable. Interesting.
I wonder if the lack of performance is because it only sees the GPS constellation on the 1575.42 MHz frequency? I have been searching trying to learn about the different GNSS services and am still a little lost on how it all works.
I think you’re right about the frequency being the problem. I’ll save the 3 antennas I have for t-beam boards which are GPS only.
I found some Beitian antennas for about $50 USD that do all 4 constellations so I’ll have to order some of those.
Sorry for this terrible Noob question but you guys seem very helpful. My gps antenna has come loose. Is it possible to reattach it?
Looks like it pulled the connector off the board, that looks pretty broken to me.
So i did some testing of 3 different Helical GPS antennas compared to the patch antenna on t-echo. All devices running SoftRF and using the SoftRF tools android app to read the real time GPS satellite connections.
All the Helical Antennas seem to pick up about 2 more satellites than the stock patch antenna. I think the main benefit will be seen under tree cover. When i have some more time, ill continue the testing.
Antennas Tested:
BEITIAN BT-1634
BEITIAN BT-660
