Tonno,
I'm not confident that the Stack Switch (or any similar Stackmatch)
has enough impedance to provide proper operation at 160 meters.
Most of them are designed for 40-10 (or 20-6) meter operation and
the impedance/isolation falls apart fairly quickly above/below the
design range.
I would look to a "designed for 160M" magic-T receiving coupler
(splitter in reverse). The receive only designs also have much
better bandwidth than the transmit power versions.
