Tilting Antennas to Reduce Line-of-Sight Microwave Link Fading

Abstract

Tilting the antennas up to obtain 2 dB loss (for each antenna) over maximum gain during steady signal conditions is shown to reduce fading over this particular path. The technique should also work on other paths where sufficient angular separation between the direct and reflected rays exists, and where antennas with sufficiently 'sharp' main beams are used.
