Howdy everyone Has anyone heard of a device such as a antenna booster that could be mounted on a building for improved reception. I have a customer that has great (CDMA) reception a block from his office, but as soon as you enter his parking lot all calls drop and the signal is lost. It's pretty annoying to say the least. It is a metal building, but I didn't think that would affect the signal in the parking lot. If anyone has any ideas on how to improve his reception feel free to post.
