44.5-5 ASSEMBLY MANUAL
Note: A cup of zince past (PENETROX, NOALOX, or equivalent) has been provided to enhance the quality of all
the electrical joints in this antenna. Apply a thin coat wherever two pieces of aluminum come in contact.
1. Refer to the Dimension Sheet. Note the different boom sections and the approximate position of each
element. Slide the 2” RING CLAMPS into their approximate positions on the appropriate boom sections. For
example, the rear boom section has three 2” ring clamps, one at 67-7/8” from the rear end. Note this section also
has a 1/4” hole (for “T” match block). Accuracy is unnecessary: the boom must be assembled for exact settings.
Spread the ring clamp fingers with a flat blade screwdriver to ease movement on the boom. Loosely add a 1/4-20
x 1” bolt and locknut to fingers of all clamps.
2. Return to the rear boom section. Mount the “T” MATCH ASSEMBLY BLOCK on the 1/4” hole, using a single
1/4-20 x 2-1/4” bolt. Orient balun connectors forward. Make sure the Driven Element ring clamp is to the rear of
the “T” match block. Now slide the ring clamp up against the “T” match block and rotate until the element channel
is on the opposite side of the boom from the “T” match block. Tighten the 1/4-20 x 1” bolt and locknut to hold the
clamp in position.
3. Sort the five 7/8” CENTER SPLICE sections: four are 30” long for use with parasitic elements. One is 15” and
is used with the driven element.
4. Select the two 3/4” x 63.26” ELEMENT SECTIONS (length specified on the Dimension Sheet for the driven
element) and slide a 4-3/8” long SHORTING BAR onto each one. Position them about 12” from the butt ends.
Slide the butt end (with hole) of each 3/4” ELEMENT SECTION halfway into a7/8” x 15” CENTER SLEEVE and
line up holes. Slide a 1/4-20 x 1-3/4” bolt through each hole and place this assembly into the Driven Element ring
clamp channel. Add the 1/4” locknuts and tighten.
5. Add the 8-32 x 1-1/4” screw and locknut and the two 8-32 x 1/4” set screws to each SHORTING BAR. Slide
the shorting bars down onto the “T” MATCH rods and position them according to the Dimension Sheet. The given
dimension is from the outer face of the “T” match block to the inner face of the shorting bar. Align the rods
parallel with th element sections and tighten the hardware. A 5/64” Allen wrench has been provided for the set
screws. Black plastic tip caps are supplied when match rods are 3/8” tube.
