The HDB4X is sold as a VHF/UHF antenna, but it is primarily a UHF antenna that will pick up VHF signals if they are very strong.

If you combine the 751 and the HDB4X with a splitter in reverse, you will most likely have problems because the VHF signals picked up by the two antennas will interfere with each other at the combining point. The UHF signals from each will also interfere with each other.

If you want to use the 751 just for VHF and combine it with the HDB4X for UHF, that will work if you use a UVSJ (UHF-VHF-Separator-Joiner) to combine them. That is what GroundUrMast suggested in post #4.

Since you haven't included a signal report in this thread or told us what channels are most important to you, it isn't possible to tell you what setup might work best for your location.
