Hello Robin: The sharkfin antennae is fairly easy to install. You just have to take your time t make sure it lines up properly. I would suggest using the tape method as the company recommends. It's well worth the effort as ytou don't want to have it pointing anywhere but straight ahead. If you have a laser level, I would recommend trying that as that would give you a perfectly straight antennae a well. The tape method is great too though if you don't have a laser level. Just don't rush! Take your time. I'd estimate 30 minutes from start to finish. Good luck!!
