Elevation Procedure
Make rough elevation adjustment using the same technique used for adjusting azimuth.
Move the antenna up or down until it points directly at the BRU. Use a mirror or strobe
light to make the opposite end more visible. Tighten the elevation adjustment nuts when
complete.

Rough Alignment During Poor Visibility Conditions
If poor visibility conditions obscure the view of the far end, it is still possible to perform the
rough alignment. The azimuth can be adjusted using a compass to aim the antenna in the
direction determined by plotting the two locations on a topographical map.
The elevation can be adjusted using a carpenter's spirit level to aim the antenna at the
horizon (level). For distances of more than roughly two kilometers, this method is often
sufficiently accurate since the far end is essentially on the horizon; for example, rough
alignment within two degrees over a three kilometer path will accommodate a height
difference of over 100 meters between the two sites.
