Web26 feb. 2024 · Line-of-sight Normally, radio signals above 40MHZ are basically transmitted in a straight line from Tx to Rx spot. This is what we call line-of-sight propagation. It is also the conventional way for VHF and UHF signals to transmit. Long-distance transmission Web- Non-line-of-Sight (NLOS) is a radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. - Obstacles that commonly cause NLOS conditions include buildings, trees, hills, mountains, and, in some cases, high voltage electric power lines. - NLOS lowers the effective received power ...
