How exactly do the “pro” RTK antennas work? I have a few areas where Yarbo gets close to the house, so I map it conservatively so it doesn’t hit the house. Do these actually get better reception? How can they? If the satellite signal is blocked (it doesn’t penetrate houses), how will this correct that?
I’m not opposed to replacing them, but I don’t see how these are going to correct blocked signals. Also, do I need to change all 3 RTK (2 rover, one data center)
Satellite signals can come from many different directions. This might give it the right amount of boost to pick up a good shared satellite that otherwise wouldn’t be seen and get you through that normal dead zone. Additionally, they have better multipath rejection, so in obstructed areas with lots of reflections, it can help filter out the noise and keep quality higher.
I would say you don’t need to replace the DC antenna unless your CNR values are 40 or below. If above, then you can probably keep the stock one. If your DC is obstructed even in the slightest, you may want to consider it.
The Pro RTK antennas can help improve GPS reception and positioning performance in both open areas and environments with partial signal obstruction. While they can’t make satellite signals pass through buildings, they are designed to better handle challenging conditions, including signal reflections and limited satellite visibility.
As Bryan suggested, you can use the CNR values as a reference when deciding whether it’s worth trying the Pro RTK antennas. Lower CNR values or areas with weaker signal quality may benefit more from the upgrade.
We’d be interested to hear about your experience if you decide to give them a try.
Where do you see the CNR value? I don’t see that in the diagnose tab.
There are a couple of spots by the house where it drifts a little bit. It may be caused by reflecting signals, but I’d like to check it.
The DC is fine. It’s up on the house and has a clear view. If I power cycle it, it is locked-in in less than 30 seconds
You can only see the CNR for the DC if you tap the yellow “Details” under the RTK section in the diagnostics. Feel free to upvote this long standing feature request asking for them to expose more information like this on the rover side (for each antenna).
Ok, so my CNR values are 36,37,38,30 for gps,bds,glo and gal respectively. I don’t have much of an issue, my rover is mostly always green with a fixed position, but on its charging pad when I initially access it, it is usually “disconnected” even though the gps sees around 20 satellites. Would upgrading the antenna fix this? I don’t yet run on a schedule as I am still tweaking my mowing areas but when I do get locked in I don’t want the schedule to not fire because of low gps at the start time.
I would replace all 3 antennas (2 core, 1 DC) and I think you will be surprised how well that will improve things for you. Your DC CNR values are borderline right now. 36 is the minimum
Just ordered three to replace all of them because, why not.
Mine always says “disconnected” for a second or two while the app is connecting. Is that what you are talking about?
I wish you guys had a write up on this. I have a LOT of trees on my property and have a lot of GPS issues. I have wanted to preorder, but it has been sitting in my cart because I don’t know what I need.
If you just copied a link to this blog and/or had a write up… i probably would have purchased sooner.
This blog (and Bryan’s explanation) was extremely helpful
Thank you for the feedback. I’m glad the topic and Bryan’s explanation were helpful.
I’ll pass this suggestion along to our team. We appreciate it!
P.S. Does this work for the Y series? I just preordered 3 as my cnr values are usually under 40 barely at 40. I’m uneasy with dead reckoning because I live right along a busy state road and I cannot have it cross the front boundary.
Support wasn’t clear if it was supported on the Y series.
It ONLY works on the Y series core, DC 1.0, and DC 2.0 RTK. The M series core will not have external RTK antennas.
I also already have three on order. In fact, I just received all new BLE, HaLo Core, and HaLo DC antennas. 
Ok… So we’re 5 days into June… @Yarbo-Forum can we get any info on when we might see these start shipping?
The store says “Delivery will begin in July.” Not sure if that was different when you ordered but it said July when I did on May 30.
Too bad I already have my order in with Yarbo. Beside, I’m not terribly fond of the warranty policy that AliExpress offers. 
I ordered mine from Yarbo instead of a 3rd party because when I have issues again I don’t want to give them the excuse of blaming 3rd party equipment. Is my concern founded? I don’t know. But it does remove a variable.
Did not say preorder when I bought mine. Then a few days later it said June for preorder. Mine arrived yesterday.
