I am getting the 996 this week. I had a RS Pro96 where I took the ducky off and put a Diamond RH77A on. The results were night and day. I gave the Pro 96 to my son as he got a sudden interest in scanning and I kept the Diamond antenna. My question is will there be an appreciable difference with the Diamond RH77CA on the 996 versus the stock antenna? I have an angle adapter I'll be using for the 996XT. An outside antenna isn't necessary with the experience I've had with the Diamond antenna. Thx guys/gals
