Pol.:			A	B

It is possible to connect transponders with A pol up to both A or B pol down (same applies to pol B). A pol stands for uplink in LHCP & downlink in RHCP. B pol stands for uplink in RHCP & downlink in LHCP. If the polarization is switched to linear, replace LHCP by Horizontal and RHCP by Vertical.
