Oh, I forgot to mention about why Escort doesn't have a rear facing antenna. It's probably because Mike Valentine owns a patent on it. However, that all changes on the 25th of this month. I don't know if Escort has plans on adding one though. Check in with their forums online. But you probably won't get a definitive answer from Escort.
