[OT] television splitter, SAT vs. U/V ANT?

[Wade Preston Shearer]

I have the following connector:

My UHF antenna is connected where it is labeled U/V ANT. My HD tuner  
is connected where it is labeled IN/OUT. I have nothing connected  
where it is labeled SAT and have no other ins our outs.

I want to connected a second tuners though and thus need a splitter.  
Wondering if I could simply flip the unit around and have the antenna  
connect where it is labeled IN/OUT and then use the U/V ANT and SAT  
connections for my two tuners. This does not work completely however.  
The tuner connected to U/V ANT worked (and thus answering the  
question that direction is irrelevant through the connector) but the  
tuner connected to SAT did not.

I am not terribly surprised as the connector is most likely labeled  
for a reason. I am curious however what this reason is. Does anyone  
know what DCPASS means? What is the difference between a UHF signal  
and one that comes from a Satellite broadcast?
