Combining OTA and analog VHF 3 on the same cable

[TheTechGuru]

I need to combine my OTA antenna and VHF 3 from a RF modulator on the same coax. When they're both connected using a splitter as a combiner OTA works fine but channel 3 is fuzzy. The fuzz goes away as soon as you disconnect the OTA from the splitter/combiner. So it sounds like what I need is a high pass filter to put on the OTA input on the splitter combiner that blocks all VHF-LO frequencies? If so, does anyone know where I can find one?

Try a diplexer, not a splitter.

What you need is a HLSJ (VHF-High/VHF-Low Separator/Joiner), but they are getting hard to find.

The HIGH port will pass VHF-High and UHF:

A HLSJ is a type of diplexer. A UVSJ is also a type of diplexer.
