materials and evenly distribute the weight.
2. Assemble NPRM frame and place in position on top of plywood.
3. Fit 4 600mm x 600mm x 60mm paving slabs into the frame, and make sure it is stable with no
movement or wobble.
TIP
Don’t fully tighten the two support braces until the weight of
the antenna is on the mount, this will ensure
