If you mean a splitter in reverse as a "standard combiner," that will probably not work. The same signals from each antenna will interfere with each other when they reach the "combiner."

You would need an expensive filter combiner to have VHF TV, UHF TV, and 137 MHz on one downlead. I suggest a separate coax downlead for the 137 MHz antenna.
OK, I think I understand now. Thanks!

These UVSJ combiners have become a bit of a scarce commodity, it seems. I did find this:

Claims .5db loss where others are 1.5db. Also passive dc pass through on both ports. Some others were only on VHF side, which doesn't work for me.

Thanks, everybody, for the pointers!
