Hello, Team GNSS.STORE
can you tell me the materials I would need if I want to start Onocoy project ? On your website there is this configuration but there are four antenna possibilities I don't know which one you would recommend: the cheapest possible but that it is good enough for Onocoy? If I understood correctly if I do not choose PoE I will power the module with a USB C cable? Can you tell me if there is a need for additional hardware for Onocoy or is everything included in the configuration? from what I understand Raspberry PI4 is already integrated into the module?
I would like the cheapest configuration but of sufficient quality perhaps you also have other materials on your website compatible with this project and cheaper?
Thanks

Dear Leam
If you are a professional surveyor, you need an antenna of the highest quality. For you – the "Choke Ring 380" antenna (ELT0314 - https://gnss.store/gnss-rtk-multiband-antennas/293-elt0314.html for just 2800 EUR

What’s your climate like? Is there snow? Can water flood the antenna? Can birds land on the antenna? Will cats or other animals sit on it? For you, we recommend the "Survey 160 mm" antenna (ELT0123 - https://gnss.store/gnss-rtk-multiband-antennas/140-elt0123.html It’s not the cheapest solution, but its design protects against weather conditions, as well as birds and animals.

If you need high quality, i.e. a small phase center, you’ll need an antenna with a long cable and a high gain factor. In this case, the "MultiPatch 100 mm" antenna (ELT0194 - https://gnss.store/gnss-rtk-multiband-antennas/267-elt0194.html is perfect.

If you have nearby buildings or trees that reflect the signal (multipath), you’ll need an antenna that suppresses multipath signals well, i.e., one made using HELIX technology. This would be the "All Bands High Performance RTK GNSS Active Quad Helix Antenna" (ELT0316 - https://gnss.store/gnss-rtk-multiband-antennas/364-elt0316.html

And if you're looking for the cheapest option, we have the ANN-MB2 antenna (ELT0317 - https://gnss.store/gnss-rtk-multiband-antennas/370-elt0317.html
