Hey
I am interested in the ELT0227 - UM980 GNSS receiver with the multi-band antenna.
- Is it possible to power the board via the I2C port?
- I noticed that the antenna supports the E6 frequency bands. What PPP convergence time can I expect with Galileo HAS compared to your ELT0316 - All Bands High Performance RTK GNSS Active Quad Helix antenna?

Dear Josef
"Is it possible to power the board via the I2C port?" - Do you mean powering the receiver via the 4-pin J2 port to communicate with the magnetometer? No, there is no +5V contact on J2. It is only on the 12-pin J1 port.
"What PPP convergence time can I expect with Galileo HAS compared to your ELT0316" - The convergence time under ideal conditions depends very little on the antenna, if the antenna receives all signals and has a small phase center. The ELT0227 uses the ELT0193 antenna https://gnss.store/gnss-rtk-multiband-antennas/266-elt0193.html

In real life… Helix antennas filter out reflected signals better. Patch antennas work well with a large groundplane, for example on a car roof.
If you have multipath (reflected signals) in the upper hemisphere - helix is better. In the lower hemisphere (reflected signals from the ground) - patch + groundplane.
