You are designing a 4.9 GHz microwave system that is using rectangular waveguide from the transceiver to the inside wall of the shelter and an antenna using elliptical waveguide from the antenna to the outside wall of the shelter. The antenna has been designed to be placed 200 ft up on a 250 ft tower. What device will you specify that will best interconnect the two different waveguides?
