RTK Antenna Options

Hi community, I broke one of my RTK antennas (review of the incident tells me it was operator error). I’ve ordered a replacement from Yarbo. I’m curious if it has to be a Yarbo specific anatanna, or will any RTK that matches the specs do, even in the interim until the Yarbos get here?

Any advice on whether these would fit the bill is appreciated.
Thanks all, the community support and knowledge base here has been very helpful on this journey already, I’ll be contributing if/when I have any valuable insights!

Yarbo antennas use L1/L2/L5 and is an active antenna. I would try something that supports all 3 bands if you are in a pinch you could try the other one, but it might have reception issues. Not sure you want to spend that kind of money for it not to work.

Those antennas work:

You sure about the L5?

Yes, they just don’t show it in the diagnostics.

Better be lucky than good then! Those I ordered were also L5 :slight_smile:

Thanks for the info. The same store has L5 antennas as well.

Actually another related question came to mind. Are there different qualities of antennas? I.e. some more precise than others? If so what spec(s) would indicate precision? Also of so, would it make any difference to yarbo?

The GNSS 901A works quite well (supposedly higher gain) and is lower profile, to boot.

Amazon sourcing is available, but time for delivery varies.

I realize that not everyone here may get the meme, but…..

I have been using the HA-901As for months now (works well), is in fact higher gain.

So I’ve been looking through some of these antennas and have noticed that there are different supply voltage ranges. Does anyone know what DC voltage Yarbo puts out on the RTK connections?

@Yarbo-Forum would have to answer this for the official voltage. But usually there is a supported range in the antennas. As long as it’s an active antenna and DC voltage, you’re probably within the standard supported range.

Well…. Unfortunately I’m seeing acceptable supply ranges from 3V-15V, to 3.3V-12V, to 3.3V-5V, and even 2.8V-3.3.V

Obviously, the 3V-12V antennas should be just fine, but when I see a higher gain antenna and the operating voltage range is only 2.8V-3.3V I get a little apprehensive about assuming the supply voltage the Yarbo uses.

I can understand your apprehension. Hopefully they come back with the official answer. I can almost assure you it is definitely not the battery voltage.

Currently testing MAN1216Q25 quadrifilar Helix antenna. Antenna is more sensitive, gps was never lost after installation. With original RTK antennas experienced GPS related pauses during the Plan all the time.
I would like also to test one more antenna from the same price category: Beitian Helix Antenna BT-560

Regular RTK like is priced ~7-10EUR in China. This RTK is priced ~25-30EUR, so its different category, price in EU/US for this should be at least 3x in retail.

PS I believe dedicated Page on forum to share info about original, alternative parts will be useful.
I was not willing to cut original charging cable to the docking station recently as its too long for my setup, but I need perfect length. So I found original dock station power connector from CNLINKO part number BD-20-J03PE-03-001A (Product name: Female Plug Only, 3P) and soldered to my 1.5mm2 3P wire. Now it looks times better and original wire is also saved.

PS2 Technical specs and details are missing for items in Yarbo Store unfortunately. I would like to know more technical details about high tech items and also details for regular items for example type of material: stainless, galvanized, steel + zn, plastic etc.

The MAN1216Q25 looks interesting, but at $50 for shipping it’s a bit spicy for me. :rofl:

The voltage is 3.3V.
