Time-nutters-- So-- How do GPS signal re-radiators work?
How do you place a GPS antenna on top of a building, pick up the signal with an LNA, amplify it to re-transmit on an inside antenna without the amplified re-transmitted signal getting back into the roof-top receiving antenna? I can see circumstances where a huge metal building (aircraft hangar?) might provide enough isolation to prevent problems, but in many cases I wonder about it... ---------------------------- As an aside note-- I recall seeing, many years ago, a totally passive TV signal repeater on top of a tall hill in mountainous territory relaying a TV station signal to some homes in a valley just below. The passive repeater consisted of an array of high-gain UHF yagis pointing to the 40 mile distant TV station tower. The yagi array was coupled to another set of high-gain yagi antennas pointing down to the homesites in the valley. I was told that it worked pretty well.
