Id like to listen to both trunked and FM
Ok, trunked in many cases is FM, but forget about that.

this may sound like a silly question, but can you use a 800 and a 2 meter antenna at the same time by using a duplexer?
Yes, you can. You can expect some loss but not a ton. You'd have to really search to find one with a VHF/800 split.

Ive heard you need the correct antenna for what your monitoring
If a coathanger lets you hear what you want to hear, don't worry about what others say. For many years all I used was a simple VHF 1/4 wave antenna so scan everything from 31-868mhz. Was it perfect? No, but it worked well enough for what I wanted so I was happy.
I use a 800mhz antenna on my pro97 in the truck and it works on VHF & UHF well enough for me, so you might find a stock antenna works well enough for both VHF & 800.
