Lay the first half of the reflector (which has the flash located at twelve o’clock) face down on the blocks of wood.

Lay the second half of the reflector face down on the blocks of wood.

Unbolt the mounting ring from the crate, and set with the rest of the parts to be assem- bled.

Improve timeliness of clean up by discarding unneeded materials while unpacking the crate. You can place all wood and unneeded materials in one area away from the instal- lation site.

Once the crate has been unpacked, you can begin assembling your Andrew earth sta- tion antenna. The reflector halves are placed next to each other to begin the assembly. The following steps provide the procedure for assembling the 3.7-Meter reflector.

Note: Figure 3-33c provided at the end of this section shows a diagram of the reflector assembly.

Station an installer under the reflector halves to begin the assembly.

See that the joint plates are clean, and then bring the reflector halves together aligning the joint-plate holes.

NOTE: The lip of one half fits over the other half, and the bolts match exactly when placed together correctly. Additionally, each half has a serial number and a red stripe that must match to ensure that you have the correct halves in the correct place.
