A 4 element yagi doesn’t have a really narrow beamwidth, but in general, if you find it difficult to aim, a yagi will have a narrower beamwidth when oriented horizontally. So, in your earlier description you could have oriented it vertically which has a wider beamwidth. This is a tweak that can help being in distant stations, but usually the other way around. Sounds like you got the cabling straight and all is well anyway.
Yaggi antenna not that great ...whats the problem??

Sounds real good with the Accuphase T109V on classical and jazz!
I don't think that the antenna choice would affect sound quality itself outside of noise if reception is poor or distortion if the signal is so strong that it's overloading the tuner's front end.
Aint that the truth, just replace everything and it will work!My guess here is either a bad balun at antenna, bad antenna cable connections (ground) or bad tuner.
There is no way a car will ever compete with a good yagi on a rotor, given a decent tuner is connected to it. As already said by PunkerX. I can get a distant MA station on my rig from 81 mi. away that is coming from over a 2600 ft. mountain range. To get it in the car I would need to drive 45 minutes east, and cross the mountain range.
I had a similar bad reception situation a few years ago, turned out to be a bad balun at the antenna. All the strong stations still worked fine. The MA station totally disappeared. Water had gotten into it and rusted/corroded the guts to the point it was shot. In less than 3 years after a new install. Installed a new balun, and all was fine again.
Also had a problem with my TV cable feed. The cabling was 15 years old. The F connector had over time corroded and pulled slightly out, disconnecting the ground. It was very subtle, and still looked and felt tight by visual inspection. Only by replacement with known good new connectors was the problem found.TV reception went from weak on 1/3 of stations to strong on all.
Don't assume anything.

This is an old thread (2010) about FM antenna problems. Since that time, the nanoVNA has become available. For ballpark $50-60 you can get one, and measure your antenna and feed line from inside the house, at the tuner end.
Maybe borrow one, or ask a ham for help if the tech stuff is too much -
or, just replace balun, cable, and clean antenna connections. As a minimum, even new F connections should be tested for continuity. It's even more important on old cables. The crimped connection to shield can get corroded and go open. Especially if you terminate your own cables.
