[QUOTE="sparky markie, post: 116835, member: 17231"] I spent 22+years as RF engineer, and over 50 years licensed extra class Amateur Radio License class. It's known as vegetation attention. It's a very real thing. By and large, the higher the frequency (lower, short wavelength) the more pronounced the attenuation effects. In my professional and Amateur experience, the worst vegitation attenuation of RF signal occurs whilst trying to do high VHF through Microwave (our links to drones) Trees and almost all vegitation absorb the frequency range we use for flight and video. Those YouTube vids of insane range tests are pretty much unobtanium from our average sites. Waaaaa [/QUOTE]
