Abstract: This invention is a method for the non-invasive and safe testing of telecommunication and broadcast towers or other airwave or cable transmitting and receiving devices and related equipment using a calibrated infrared camera and computer, computer software, a color monitor or a color printer. This novel method of testing and determination of potential problem sites and failure prediction can be conducted from ground level and at some distance from the tower or device being tested, substantially reducing the risk of falling from extreme heights or being exposed to hazardous EMF fields, microwave or RF transmission waves, all of which are fatal or hazardous to health of the person conducting the testing.
