That’s a lot to consider. A few points to consider..
An antenna analyzer is not cheap. They’re wonderful instruments and way, way better than an SWR meter, but you’re looking at several hundred dollars.
I’m not familiar with any automatic antenna tuners that work at HF/UHF frequency ranges. One antenna to cover 108 all the way up to 160 Mc isn’t optimum, but not unreasonable. However covering 450 Mc is really a different antenna.
In general where an antenna is can be much more important than what an antenna is. It sounds like you’re using a telescoping whip antenna inside the house. There are a lot of obstructions between your antenna and whoever you’re trying to listen to.
I’m not really coming up with any solutions for you here, sorry. Just some thoughts before I get my first cup of coffee.
