u/Ill-Situation-1985

I purchased a 2026 Ram 1500 Bighorn and I'm looking to get this as my first cb radio. https://a.co/d/0ct42D3v . I want to mount the radio on my dash and the antenna between the cab and the bed. Looking for advice on what antenna to purchase and if anything else is needed. If it matters the truck is the Quad cab with 6'4" bed.
