It just depends on how much experience you have with window tint, in my opinion. If you don't have much experience, I would suggest just taking it some where and having someone professional do it. That back window is gonna be a bitch. I know people that have used the tint that you would get at like an auto parts store and in no time, it turns to a purpleish color so if you want it to last, and I'm assuming you do, I'd just go ahead and pay someone that knows what they're doing and that will use a professional tint. As far as the tint interfering with the antenna, I haven't had any problems and my windows have been tinted since the day I drove it off the lot, which was 3 years ago. Hope this helps!
