H-field pre-amplifier PCB and ferrite antennas
#1
For the system blue H-field pre-amplifier PCB - a few questions:


1.  Do the ferrites connect between just the a and b ports with the ground port left unconnected unless additional shielding is needed?

2.  Is there any polarity to the ferrites - I see references to one enameled wire with a knot being + or is this for the old system only.

3.  For ferrite antennas do the PCB jumpers need to be soldered (closed).


Thanks in advance!
