ctor in transmission. This result can be seen with your home radio. The sun reduces the elevation of the Ionosphere (a field of excited particles in the atmosphere) during the day, but at night the ionosphere rises again allowing radio waves of large wavelength to go many times further than during the day, because of Tropospheric bounce ( where radio waves are transmitted bounce between the ionosphere, and the ground, allowing long distance communication.) That is why Short wave radio can be heard around the world. This phenomenon is most prevalent around the 14MHZ range. Solar activity will affect most any radio transmission, sunspots, rain, and snow will affect microwave communication especially. Particulate matter will affect microwave more than lower frequency transmissions, because of its narrow wavelength it has closer properties to light waves (line of sight).Interference is an obvious distortion in signal quality as well. Interference results from other transmissions no matter what transmission medium used. Antenna systems are also a key element in the microwave system. Omnidirectional Dipole Antennas provide 360 coverage. These types of systems Beken 8are typically mounted on a mast. Omni Antennas have a very narrow elevation when dealing with microwave transmissions, both the height and distance separation between the two sites mist be taken into consideration when selecting this type of antenna. Parabolic Dish antennas provide high gain directional transmissions. Parabolic antennas provide narrow sectorization, and are quite hard to align.Sector Panel antennas are the best choice when several wide angle coverage sectors are needed (typically seen cell towers) There is normaly a drop in antenna gain at 90, so the antenna coverage needs to be overlapped. There are many vendors that provide Microwave networking systems. I have had significant experience with several systems in the military specifically several of...
