HFTB436CP42-2X2 ASSEMBLY MANUAL
All installations are unique in some way, which means it's OK to preassemble certain
hardware, or rearrange the assembly process to meet specific site requirements. A quick review
of the assembly notes and drawings should help firm up the appropriate strategy. Please
remember to double-check all hardware for tightness BEFORE it becomes inaccessible.
These notes assume an assembled cross boom of adequate dimensions and U-bolts of the
same size for attaching H-frame plates. Unless you ordered a COMPLETE M2 'H' FRAME. If you
just ordered the vertical booms and specified a cross boom U-bolt size when ordering, some
drilling or other fabrication may be necessary. Stainless locknuts or nuts and lock washers are
supplied for all kit U-bolts. All other assembly hardware is stainless steel unless otherwise noted.
Forged steel parts are galvanized.
REFER TO THE 'H' FRAME DRAWING AND THE 'T' BRACE KIT DRAWING FOR PLACEMENT
AND HARDWARE CALLOUT.
VERTICAL BOOM ASSEMBLY.
1.
A 1 1/2" x 24"' FIBERGLASS MAST EXTENSION is inserted into each end of the 2.0" x 32"
CENTER SECTION. Build two (2) of these assemblies.
2. Mark the center of each 2.0" x 32" vertical leg with a marker pen or equivalent. Attach a 1/4" X 4 X
6" VERTICAL BOOM MOUNTING PLATE at the center of each vertical leg, using 2" u-bolts and
cradles.
2" MAIN BOOM PREPARATION
1. If You are using an Elevation Mechanism, Slide the 2" x 72 main cross boom into the elevation unit
and center.
MOUNTING VERTICAL BOOM
1. Attach the VERTICAL BOOM assemblies to each end of the MAIN BOOM, noting the correct
spacing for the antennas in the array. NOTE THE ANTENNAS MOUNT ON THE OUTSIDE OF
THE VERTICAL BOOMS. Also and more important, align each vertical boom with the other so
when all the antennas are mounted, the left side of the array will point at the same point as the
right side. Some tweaking of all alignment and balancing will probably be necessary once the
whole array is assemble and in place on the main boom.
