PREPARATION FOR ASSEMBLY
FOR OVERSEAS CUSTOMERS: If you use the
Metric System, see the American-to-Metric
conversion table in the rear of this manual. Most
illustrations in this manual will provide bcth
American and Metric Dimensions.
Make all measurements to the given dimensions,
plus or minus, not more than 1/16 inch! The
assembly of this antenna will be easier if you
read this manual completely through at least
twice and follow the recommended directions.
Allow at least 4 hours for assembly.
Choose a moderate-sized clear area to assemble
the 215DX Beam. The area must be at least 5' x
6' (1.5 m x 1.8 m) for each boom section. A
bench-vise is recommended to hold the booms
while the elements are being installed. An
alternate method is to drive a 5' (1.5 m) length of
mast material into the ground and attach the
entire boom and boom-to-mast bracket to this
mast temporarily during assembly. If you
assemble this antenna over a grassy area,
precautions should be taken so that hardware is
not accidentally lost during assembly. A concrete
driveway is an excellent area for assembly.
Tools: The following
tools
are required for
easy assembly of the 215DX Beam:
Qty
Tool Type
1
Tape measure, 12 ft.
I
Nut Driver, 1/2 in.
1
Nut Driver, 7/16 in.
1
Nut Driver, 3/8 in.
1
Nut Driver 11/32 in.
1
Screwdriver, small flat blade
One nut driver should have a hollow handle.
This can be used for pushing on the
pushnuts. Standard 'wrenches or adjustable
wrenches may also be used in place of the
nut drivers.
ASSEMBLY OF THE BOOM-TOMAST
BRACKET AND BOOM
Select the boom sleeve, insert, and splice, boom
sections and mast bracket parts as shown in
Figure 3. Line-up the holes in the 6 boom
sections as shown. The #3 and #4 boom sections
should meet at the center of the boom-to-mast
brackets for best wind area balance.
The boom sections can be identified by their
length and diameter. The mating ends of each
boom section can be identified by the element
mounting hole reference dimensions as shown in
Figure 2.
If the elements are to be installed in the boom
sections indoors, label each boom end with
masking tape at this time, and assemble the
boom sections together when the antenna is
ready to be attached to the mast.
If the elements are to be installed in the boom
outdoors, assemble the boom sections together at
that time and tighten all hardware securely.
When unpacking your antenna, check inside of
all tubing for small parts and elements. To
conserve space, these smaller articles are
sometimes put inside larger pieces. Check all
parts against the parts list in the rear of this
manual to ensure no parts are missing.
