ANTENNA ASSEMBLY
BEFORE YOU BEGIN
1. Select an assembly area large enough to comfortably accommodate overall
antenna dimensions. A shallow box is handy for holding and sorting the smaller
hardware, as is a marking pen for identifying components.
2. Some simple tools are required: a tape measure, screwdriver, and a set of
spintite, socket, or end wrenches. Common nut sizes are:
5/16" = 6-32 hardware 7/16" = 1/4-20 hardware
11/32" = 8-32 hardware 1/2" = 5/16-18 hardware
To avoid damage to antenna components, be aware that most hardware needs
only be moderately hand-tightened with screwdriver or spintite to be secure. When
using tools with mechanical leverage, such as socket or end wrenches, care must be
taken not to over-torque nuts and damage components.
3. Thoroughly unpack shipping box and check components and hardware against
the Parts List. If there is a difference, look for a "Factory Update/Change" sheet
accompanying the assembly instructions prior to contacting your KLM dealer or the
factory.
