The multi-track problem is exaggerated. It appears only at modern constructions and on the water. In forests, or rather on forest roads, this problem does not exist.
The example here concerns the use of the ReachM module in the AzusRTN receiver as a rover, the base is VRS. The choice of antenna for such a module is important.
If we want to use a ground plate for our receiver then it must be 3D, not 2D (i.e. aluminum foil). The cheapest alternative is probably to put an abrasive disk for metals,
because the choke ring is not an option.
But it’s best for the antenna to have an electronic circuit with down quickly gain control near the ground and enhanced multipath signal exclusion.
