So I would frequently have my GPS drop out or get weak even in open areas and take well over 10min to recover once moved to a open area manually.
I decided to give a different antenna a try and purchased 2 Waveshare Q39 antennas to replace the stock ones, I immediately noticed a difference, I can actually drive the yarbo about 10-20ft into a heavily wooded area and still have signal(sometimes drops to mediaum) but recovers almost instantly once back in the open.
I also had purchased a Q25 for the datacenter but have yet to climb my tower where the datacenter lives and change it out.
I did not realize how much of a size difference there was between the Q25 and Q39 but the Q25 seems almost identical to stock.
If you 3d print one of the RTK reinforcement/protection’s it will likely be too tall for the Q39 but almost the same width so it looks like it was made for the yarbo.
Is this what you’re referring to? I’ve been having issues with spotty GPS connectivity, even though there are 18 or more satilites in view. Sometimes it seems to work well, other times not at all.
Those are the pro, better reception. System uses 3 total, 2 on rover, and 1 on DC. You might be able to skip the dc but I got 3, figured if I break one I can steal the one off the dc and put an old one back on
I have had HA-901A antennas on the core without risers and a HA-609 on the Data Center for around a year and they work considerably better… I am not sure if those are the same specs as these and what Yarbo is selling… but they are the same or very similar form factor.
Honestly the first ones I found that covered all the bands of the stock antennas… looking at the Q ones, some of the bands are different… but may be ones not used by Yarbo… if it covers all the bands Yarbo needs then I think they are a better choice as they seem cheaper.
Those are the ones. Would you mind sharing some screenshots of your diagnostics when you’re having trouble? RTK, status, Data Center, HaLow sections. Then tap the yellow details under the RTK section, connect to your DC and screenshot your scatterplot. Maybe we can figure out what might be going on or where to best focus your efforts.
You probably need a new right antenna (as you face the rear of the core). Your L2 should not be zero. HDOP is really high. Surprised it works at all TBH. DC looks beautiful.
If you’re going to replace with the Pro antenna, I would replace both core antennas. DC isn’t needed unless you want to since your DC CNR values look great. For now, I would recommend replacing the right with a spare of the original one until the Pro is shipped. Currently on preorder for July.
Brilliant - I’d forgotten I even had them, as I originally set it up with the long ones for snowblowing. GPS came up fairly quickly after a system restart. Meanwhile I’ll order a pair of the new ones. Thanks!
