i saw some previous posts about the BT-560 Helical antenna and the F9P RTK. Has anybody tried it yet? Also does this antenna needs a ground plate (my guess is that it doesn’t). Lastly is the “GNSS Multi-Band L1/L2 Surveying Antenna (TNC) - TOP106” antenna going to make a big difference to the performance of the F9P base station or the “classic” u-blox GNSS Multi-Band Magnetic Mount Antenna - 5m (SMA) with a ground plate will have similar results?
