I took this image from old thread as did not want to hijack it. I wonder if someone could provide simple formula similar to formula in Sketch 1 for Sketch 2. Basically I’m trying to answer question how “visual” range changes if we put obstruction between antenna 1 and antenna 2.
h1 - antenna 1 height
h2 - antenna 2 height
H - obstruction height between antenna 1 and 2
L - distance between antenna 1 and obstruction
