I was reading about those and I noticed some comments about the splitter causing a weaker signal. Have you heard anything like that?

Thanks for the help!

Here's the comment I'm referring to:

Question: Does Digital Antenna offer an AM/FM and VHF splitter or band separator for use with a VHF antenna?
Solution: A VHF/AMFM splitter drastically degrades the VHF performance. Digital Antenna does not promote such a function. VHF antennas are your lifeline and it is never wise to degrade the performance. A splitter to combine frequencies should never be used especially when the systems are not even the same impedance. VHF is 50 ohms and AM/FM is 75 ohm. Combining two different impedances creates an instant mismatch which detunes the antenna performance. As with any 2-way splitter, a minimum 3dB loss (50% power loss) is present. This loss drastically cuts the performance of a VHF antenna. These laws of physics can not be avoided. Digital Antenna does not recommend using a VHF/AMFM antenna splitter.
