ASSEMBLY INSTRUCTIONS

Unpack antenna and locate the hardware package. Some antennas are shipped in
two sections, in which case the boom is broken between directors 21 and 22. Remove D21

D22 elements, align and retighten. Note the boom markings for correct assembly order.

Straighten any misaligned elements and tighten hardware if necessary.
