I am glad this came up. I was planning on installing a GPS antenna that looks like a miniature computer mouse. It could mount on the louvers (or even under them) but because urethane is supposed to be invisible to radio waves I was thinking of installing duel antennas, in the front and rear fascias. The antennas will probably have to be mounted the correct side up and might need some kind of mount to orient them the right way. I don't see why any antennas can't be mounted in the fascias. The only problem I can see is that they will not get 360 degrees visibility so a duel setup with one front and rear might be the best. Be careful running the cable not to have any sharp angles or running it close to sources of RF interference. - Mike #17084 (gov't computer fix-it guy) To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
