Earth curvature line of sight

WebRadio that is in the VHF band travels in a straight line. In other words, the rays travel using line of sight. If two users on the opposite side of the world want to communicate, the radio wave cannot use line of sight propagation, because it travels in a straight line and will not go around the curve of the earth. Web“@ryky434 @anotherbigmike @globe_4_life @French__Raven @marshray @Its_only_Bob I've done line-of-sight radio transmission that doesn't work past earth curvature. My dad bounced HAM signals off the moon to get around line-of-sight. I've trained to launch nukes at the Fulda Gap out of line-of-sight. You have no idea what I've tested for myself.”
