Not for telemetry.  That one looks more like a sharkfin.

The antenna there is for cellular or radio RTK connection or if it's cellular also for wireless TaskDoc export to PTx Farm Engage/Trimble Ag Software.  Doesn't get used a lot in NA as many of our implements don't use ISOBUS/TASKDATA for documentation.

I've used that antenna mostly for NTRIP RTK as you can put a sim card in the factory steering controller and connect to the VRS network of your choice.
