You get that from OFFROAD COMMUNICATIONS? That's where I got the exact radio with antenna, mount, magic mic holder, coax, adaptor and plug and play wiring harness. Only thing I had to come up with was ground wire for antenna and ROP clamp, he's a vender on this site.
Actually I got the radio from eBay and antenna from Amazon I also bought a marine amplified external speaker too but the radio is loud enough without it
