Default VHF AM/FM Antenna splitter

I recently purchased a 2001 Parker 2510 and working through electronic upgrades. While installing new VHF antenna I realized the am/fm and VHF antenna cables go through band splitter. I have horrible am/fm reception both before and after new antenna install. I have full confidence in cable connectors. Questions:

1. Do the band splitters go bad, and how effective are they?
2. Would the band splitter have any effect on VHF reception?
3. I have plenty of antenna mounting space. Would I expect a benefit from simply using separate antennas? The VHF obviously takes precedence but listening to decent tunes while trolling endlessly is important too...

Thanks for any input

I tried one of those splitters, in fact I still have it. I don't know if they go bad, in my opinion they are bad right out of the box. I had an old VHF connected to an older antenna and I wanted to put in a new VHF with a nice new antenna. The old VHF and antenna didn't have a splitter on it. When I installed the new VHF and new antenna I put the splitter in line in the antenna cable.

The old VHF was way better at sending and receiving VHF communication than the brand new one. I tried to use the splitter as an FM radio antenna and that didn't do anything to pull in FM stations. As far as my experience they are junk. Because I was able to compare the old VHF with the new VHF I know the splitter reduced my VHF range significantly.

I still have the one I bought, if you want it let me know.

Didn't bother with splitters. Installed a separate vhf and am/fm antennas. I couldn't pull any nearby stations without the am/fm antenna, but with it, I get pretty much all the ones you can get with your car. Very happy with the reception.

Don't comingle emergency electronics (VHF) with entertainment electronics...get rid of splitter, get antenna for AM/FM, even if it's just a twin-lead one included with the head unit, or $3 shipped on eBay.

Safety vs. tunes? Make a choice.

Emotions aside, any impedance mismatch and cable loss negatively impact the reception of radio signals. Surely the splitter impacts reception and transmission of your VHF radio, it is possible that the impact is small. I would eliminate the splitter and keep the VHF radio system isolated regardless of loss.
